Complete Version history / Release notes / Changelog for DVD Decrypter Released: 21st March 2005
* Added: Support for setting the read speed on AOpen 1648 DVDROM drives.
* Changed: Creation of an MDS file is now only 'forced' when ripping to a FAT32 drive (like how it was in, rather than when also ripping a DL disc. A warning has been added to the 'Create MDS File' option in the settings instead.
* Fixed: 'Layer Information' being shown in ISO Read mode when there was an empty DL disc in the drive - it shouldn't have been!
* Fixed: Hang on some usb/firewire drives (enclosures).
* Fixed: Error on some 'dummy' images mounted in DAEMON Tools - caused by non standard UDF file system.
* Fixed: Start button still being enabled in File mode even when no files were found.
* Fixed: Problem of the burn aborting if 'Lock Volume For Exclusive Access' failed silently with a 'known' error. People who experienced this problem should really just upgrade their IDE drivers. 18th March 2005
* Added: Support for detection of newer / other forms of (possible) structure protection.
* Added: Support for removal of structure protection from IFO/BUP files. So ripped files will import into any processing software (and by that, I mean CloneDVD etc!)
* Added: 'Layer Information' to the info panels in ISO Read/Write modes. Displays number of sectors on each layer + percentage of overall disc size.
* Added: Destination -> 'Capacity' + 'Free Space' labels now have tooltips that show the value in bytes (rather than KB as shown on the actual form).
* Added: 'Application Identifier' to tooltip when you hover over the volume label in the 'Source' box. This also gets put in the log when you perform a read/write operation.
* Added: 'Implementation Identifier' to tooltip when you hover over the volume label in the 'Source' box. This also gets put in the log when you perform a read/write operation.
* Added: Workaround for drives connected via firewire that donít support the real time streaming commands ('get performance' and 'set streaming' - these get / set the read / write speed). The 'set streaming' one can hang the entire bus if connected via firewire. Power (of entire machine) must then be cycled.
* Added: All burners are now issued a 'SET STREAMING' command when make them read at full speed - even when not specifically told to do so via the option in the settings. Too many cases of PlexTools PI/PIF scanning putting the drive at 2x!
* Added: A 'Quick OK' button to the 'Create MDS' file dialog. It wont prompt for a file name, just take that of the first image part and change the extension to .MDS.
* Added: Option of selecting SAO or Packet/Incremental for 'Write Type'. Useful for drives that prefer one over the other. Currently the Pioneer 109 doesnít make good discs using SAO on DVD-R media. XBOX and old standalones cant play them.
* Added: Option to enabled / disable the OS wide 'Autorun' property for CDROM drives
* Added: For people that like to install the app, copy the exe somewhere and then uninstall, I've made the program check the 'InstallDirectory' registry key and create it if needed each time the app is opened / closed. This key is used by other tools like DVD Shrink to check DVD Decrypter exists etc.
* Added: Support for PSL v2.0 (Import + Export)
* Added: Aborting the decryption process whilst the drive is doing read retries now displays the error the drive finally comes back with.
* Added: Workaround for AOpen drives that wont authenticate sometimes.
* Added: Select IFO, BUP, VOB to 'Edit' menu in File mode
* Added: 'Recording Management Area Information' to ISO Read / Write info screens. Displays (where supported), which drive burn the DVD-R / DVD-RW media in the drive.
* Added: Support for split (i.e. FAT32) NRG files.
* Added: '.CDI' type images to the list of supported image types. The '.CDI' format is used by discjuggler.
* Added: Option to enabled / disable 'Plextor SpeedRead DVD' via the Tools -> Drive menu (+ right click context menu on drive drop down box).
* Added: Support for a 3rd variation of bit setting on LiteOn drives.
* Added: 'Ignore Unreferenced VTS Sets' to File mode settings.
* Added: 'Uncheck Suspect Cells' to IFO mode settings (on by default).
* Added: Ability to hide pack header warnings in 'structure protected' areas.
* Added: Option of specifying chapters for IFO mode via '/CHAPTERS' in CLI mode. (forgot it was in!)
* Added: Option to cycle the tray once dummy sectors have been inserted due to a protected disc. This should make the drive spin-up to max speed again.
* Added: Option within the Installer to create shortcuts for all users, not just the current one.
* Added: All the items from the 'Device' context menu to a new 'Drive' submenu in the 'Tools' menu.
* Changed: Structure protection detection code works with AnyDVD now and won't report protection that AnyDVD (or other programs) has removed.
* Changed: Updated Patin-Couffin code to use latest IOCTLs - faster and cleaner now. Requires Internal Revision 27 (or above) now for NT based OS's.
* Changed: Tweaking of Authentication -> GetTitleKey routines.
* Changed: Program update code to work better for people who use a proxy to connect to the internet.
* Changed: Patin-Couffin interface now displays SrbStatus too in I/O Error dialog.
* Changed: The program no longer cares if the GetASF function fails.
* Changed: All I/O is now sent in a properly alligned (by the VirtualAlloc API) buffer.
* Changed: The Drive Ready -> Not Ready code to force a dismount of the volume when using SPTI as the I/O Interface.
* Changed: Tweaked Plextor bitsetting code.
* Changed: Program update code now looks for an internet connection before attempting to open a connection to the update servers. This will stop the 'Dial Up' connection boxes from popping up during automatic program update checking.
* Changed: Program update code now looks for and attempts to use the IE proxy settings before then attempting a direct connection to the update servers.
* Changed: Volume Label changing code has been updated to use additional UDF descriptor values to know how much to scan for File Set Descriptors.
* Changed: 'Enable/Disable Regional Code' code for LiteOn drives - now supports more drives.
* Changed: Cell 'layer' property (used in 'By Layer' file splitting) is now calculated via the real media layer break instead of the 'seamless playback linked in PCI' flag of the cell in the IFO file. The old method was very inaccurate.
* Changed: Max buffer size from 128MB to 256MB
* Changed: Now issuing 3 different 'Set write speed' commands, using slightly different values for each. God knows which one (if not all?!) is the right one - hence the reason for 3 ;)
* Changed: Loading ISO images when an MDS file exists no longer causes the program to tell the user to load the MDS file if the image is < 4,700,000,000 bytes in size.
* Changed: Code to work out the best 'Transfer Length' value.
* Changed: When 'Software Write Error Retries' is anything other than 0, the initial error is now saved and then displayed in the I/O Error dialog box after retries have been exhausted.
* Changed: Full erase (format) on DVD+RW discs now waits for the entire (foreground + background) process to finish before saying it's complete.
* Changed: The 'Open File' type dialog boxes are now created with an additional flag to make them check the file exists before letting you click 'Ok' and then them closing.
* Changed: Entries in the list box in File mode are now sorted by VTS set, with IFO first within a set, then VOB then BUP. This is instead of them being shown in the order they're in within the file system.
* Changed: Installer now checks to see if DVDDecrypter.exe is running before attempting the installation. It'll prompt you if it finds that it is, and ask you to shut it down.
* Changed: Default sectors to search for CSS in Brute Force mode is now 500.
* Changed: ISO Write mode no longer sends a modified Write Parameters page to the drive when using plus format media. Going by the MMC specs, an application isnít supposed to (I think!), the drive configures itself automatically.
* Changed: All 'Read' modes now put 'Extracting Sectors...' in the log having completed 'Inserting Dummy Sectors (x - y)...'. Too many people thought the program was getting stuck actually inserting the sectors rather than the REAL reason that it couldnít read the next sector after them.
* Changed: The drive locking code will no longer error out if the error code is 'Invalid Function'.
* Changed: 'Structure Protection' detection code to hopefully pick up less 'false positives'.
* Changed: Handling of bad sector areas as part of the structure protection code.
* Changed: Some of the AutoPlay integration code for XP / 2003 etc.
* Changed: MDS file association is now on by default.
* Changed/Fixed: 'Rename' is now the default button (rather than 'Yes') in the 'This file already exists, do you want to overwrite it?' dialog box.
* Fixed: A file could have its 'Handle' left open if doing a DL disc that made use of 'calculate optimal' for the layer break. If the program is also then told to delete the image after burn, it would fail because the file would be in use.
* Fixed: ElbyCDIO interface could report incorrect SenseArea info.
* Fixed: ElbyCDIO interface errors (non CDB command ones) could have been misreported.
* Fixed: Access violation when a chapter in the IFO said it used cells that didn't exist.
* Fixed: (workaround for a) problem with authentication on some Asus DVDROM drive with v1.07 firmware when a certain file wasn't encrypted.
* Fixed: Access violation if you close the program while the program is searching for devices.
* Fixed: Potential access violation due to 'PlaySound' API being limited to 256 characters in the file name.
* Fixed: Got 'Minimize to system tray' working on system menus in Windows 95. It wasn't being added to the menus before. :-(
* Fixed: Windows 'please reinsert the disc' message once the disc has been ejected and before the 'Operation Successfully Completed!' sound/message. (Hopefully fixed anyway!)
* Fixed: Problems with LiteOn DVDROM drives that misbehaved and gave random pack header errors and failed to patch ifo/bup errors (maybe only a USB issue).
* Fixed: Problem with using 'cut' on log entries
* Fixed: Switching to the LiteOn tab in the booktype setting dialog issued commands that weren't used / needed.
* Fixed: Potential problem where some drives would show 'Unknown' for 'Current Profile' due to some error catching code that caught errors that weren't really there.
* Fixed: Workaround for Change volume label 'hang' on Nero UDF and UDF/ISO data images that don't have a 'Terminating Descriptor' after the 'File Set Descriptor'.
* Fixed: Made sure you can't switch program modes while another switch is taking place - this was possible before (if you had mega quick fingers) and crashed the program!
* Fixed: NEC temporary bitsetting wasn't allowed unless another program had already set it for that media type.
* Fixed: Devices drop down list staying disabled if user experiences 'Device Wouldn't Open!' error message.
* Fixed: Infinite retry loop in the 'GetFileSize' function - only happened when the API command failed.
* Fixed: Some of the 'Save' dialog boxes didn't force a file extension to be added to the file name if one wasn't specified.
* Fixed: A minor issue where under certain circumstances, selecting 'Rename' in the 'file already exists' dialog box wouldn't create the 'destination file has been renamed to xxxx' entry in the log.
* Fixed: A bug (but not really a bug as the code didn't exist before!) with some drives that show blank media as having a status of 'Incomplete' instead of 'Empty' but then had a session status of 'blank' - this IS allowed, but very rare - hence why I'd not seen it / implemented it earlier.
* Fixed: Strange 'jumping' when the log window is resized using the top bar.
* Fixed: Windows NT 4 ALWAYS saying I should have selected the MDS file rather than the ISO, even when one didn't exist.
* Fixed: A problem with 0 byte files and Start LBA addresses of 0 messing things up in ISO Read mode.
* Fixed: Bug in the program update code that would mean it still tried (and retried) every link (3 of them), even if you were trying to exit the program - would lead to a 'Waiting for Program Update Thread' message in the status bar for days on end!
* Fixed: A bug in the function called by specifying '/chapters' as a CLI option. DVD Decrypter would crash on exit on Windows 95, 98, Me, NT and 2000.
* Fixed: Bug in volume label changing code (UDF filesystem) that would mean a longer name would get truncated by windows when displayed in 'My Computer' etc.
* Fixed: (I think) a problem where the program could get stuck reading as a result of the 'structure protection' code combined with a real read error in a certain place. 5th January 2005

* Changed: Window snapping so that it snaps on the middle of the screen and not just at the edges
* Changed: 'SetWriteParameters' function to attempt to use the drive specified 'link size'. Also changed to hopefully fix some total failures in setting the parameters on certain drives
* Changed: Write retries have been reintroduce (old default = 0, new = 20)
* Changed: Drag + Drop code enabled / disabled at different times to help prevent some subclassing problems due to ThemeManager - could cause access violations on some PCs when the app is closed
* Changed: Added another URL to the 'check for program update' code
* Changed: Behaviour of 'Browse' dialog for ISO Write source files. It will now select the nearest folder to the one last selected
* Changed: volume label change code to support split image where the backup volume descriptor is at the end of the disc
* Fixed: A bug in the 'check for program update' code that could mean 1 failure causes all the retries to fail too
* Fixed: UDF volume label changing code to recalculate descriptor CRC + checksum
* Fixed: Major slow down on some 'structure protected' discs
* Fixed: A problem with some DVDRAM discs, reading them to images and trying to change the volume label Released: 2nd September 2004
Added: Ability to Import / Export PSL (Protected Sectors List) files (Option is located in the 'File' menu). Users can work out the best methods to backup certain 'problem' discs
Added: Dialog box to remind users to load the MDS file instead of the ISO file - it's good practice and is vital for nice DL burns
Changed: Structure Protection code to find more instances of 'suspect' areas on the disc
Changed: Some of the Automatic 'Transfer Length' code. It now checks for additional possible errors in the output from the API call
Changed: Previous workaround for Plextor PX-712A authentication problem caused problems for old drives that hang on a 'Rezero' command (Status bar always displayed 'Almost Ready'). The command now only runs on Plextor DVDR drives

Changed: File mode 'Detect Mastering Errors' now works like IFO and ISO modes and still checks each VOB/CELL ID change even when the file isn't supposed to be protected
Changed: Handling of ripping process in IFO mode. It now wont care if the 'VTS Cell Address Table' doesn't match the PGC
Changed: Browsing for a destination folder will now default to the closest folder to the currently selected one instead of going to the desktop
Changed: Clicking on the hdd icon to the left of destination will now open the closest folder to the currently selected one instead of doing nothing if that exact folder didn't exist
Changed: Added a little work around for Plextor PX-712A drives that can come up with a 'failed to get varient' error during authentication
Changed: Code for 'Opening' of device in SPTI mode
Fixed: Protected DVDs (ones with corrupt IFO tables) could/would have had one of the corrupt PGCs being selected as the 'Main Movie' one
Fixed: Unused cells from the start of a PGC would have been copied in IFO mode when they shouldn't have been
Fixed: Data buffer overflow when setting the hardware read error retries count

Added: A log entry for the 'L0 Data zone Capacity' when burning DVD+R DL discs
Added: A new option to the 'ISO Write' page in the settings - 'Cycle Tray Before Verify'
Added: Crash recovery for 'Checking for RCE Protection' code - so corrupt IFO files shouldn't mean the disc can't be copied - as all other IFO parsing can be avoided if required
Added: ISO Read / Write modes now display the % done of a background format on drives that support it. It will say 'Formatted: No (In Progress) (X% Complete)'. You have to perform a 'refresh' to make it update
Added: 'F8' now enables/disables I/O Debug Mode
Added: 'F9' to minimise the program to the system tray
Added: 'F12' to load up another instance of the program

Changed: Detection of 'end of disc' in ISO Read mode during the actual read phase. Implemented support for an additional error message
Changed: Detection of drive capabilities to work with drive that don't error out on a certain command but instead return blank information. This would previously have meant the drive would come up as 'Unknown' during initial drive scan
Changed: The order of a couple of commands in ISO Write mode. Aborting a failed 'exclusive lock failed' command would have left the disc in the 'Incomplete' state (i.e. non burnable) until you ejected / reinserted it
Changed: The volume is now dismounted and locked when it's locked in exclusive mode
Changed: The duration of exclusive locking. It now locks during verify too
Changed: Unsupported files in ISO Write mode now display more information as to why they're not supported
Changed: The method of finding out the current type of disc - so it may change the information in ISO Read / Write modes for burnt discs. (Bits may have been missed out in previous versions)
Changed: 'RCE Protection Found' dialog box to include ALL region. The program now also greys out options that aren't applicable - i.e. if the media isn't region 1,2,3,4,5,6,7,8
Changed: File mode logging when 'Detect Mastering Errors' is enabled. It now shows the correct LBA for the disc instead of for the file. (Keep things standard throughout the program)

Changed: 'Pack Header Not Found' warnings are now also shown in ISO Read mode so as to warn the user of potential problems
Changed: What's displayed in the info panels in ISO Read/Write mode is now not so dependent on what the 'Current Profile' is. It now also works by the discs 'Book Type'
Changed: Some of the code behind setting the drives 'Write Parameters'. This may work out better for people who said they were having bad burns from
Changed: Some of the disc initialisation code to use single commands to get and display the 'state' of a disc (i.e. Empty, Complete), so that what's displayed in the info panel in ISO modes is what the program uses.
Fixed: Problem with drives (i.e. AOpen ones) that make use of multiple AGID values as part of Authentication
Fixed: Write speed control wasn't correctly being set to its last saved value
Fixed: Older Pioneer writers (i.e. Pre 107) weren't burning some CD images properly
Fixed: Ejecting the disc after erase, before burn - it shouldn't have been happening
Fixed: Problem with invalid characters in filenames (generated from the disc's volume label)

Fixed: Authentication on some discs would just repeat over and over again during reading without any error
Fixed: Polling for completion of certain I/O at the end of a burn in ISO Write mode would fail on certain drives
Fixed: I/O Errors using SPTI where the actual API call failed would often mean sense area information wasn't displayed in the dialog box
Removed: The option to 'Force CSS Present' - This has been made obsolete by recent improvements
