v2.5 (2025-06-01)

Highlights:

DVB subtitles (can be displayed only when using VMR9, EVR or MPC Video Renderer)
added support for “MPC Video Renderer” https://github.com/Aleksoid1978/VideoRenderer To use it in local mode (without registering in the system) download a release archive and extract MpcVideoRenderer.ax into folder \AltDVB\Filters\MPCVR\
new decapsulation method “TS-TS” : transport stream embedded into payload of packets from one PID, with optional decryption using fixed CW (see \Configs\DecapKeys.txt)
reworked teletext subtitles parser and renderer, also require VMR9/EVR/MPC-VR to display
re-added audio A/B switch option, using internal directshow filter
new scheduler uses Microsoft Task Scheduler 2.0 API (Win7 and later) and no longer depends on AltCMD.exe
Other changes:

DvbAvSrc.ax filter is now integrated into the main application
restart playing after the video window is moved to other monitor (VMR7,VMR9,EVR)
new scanner window layout; more logical & ergonomic buttons position i.m.o.
when entering scanner the main channel A/V is keeped active until tuning to another frequency
re-tune to the last channel when exiting the scanner window.
scroll with mouse wheel when hovering over the control (in MainForm, Scanner, EPG Viewer)
configurable mouse middle click action; default: MiddleClick=toggle floating window, Ctrl+Middle=toggle mute
stay-on-top option for floating window. Single click on tray icon brings window to front.
hotkey Ctrl+F to focus “find channel” edit box
hotkey Ctrl+J to toggle video renderer statistics (right now works only with MPC-VR)
when channels are grouped by “Frequency” the parent node shows decapsulation parameters (if any)
volume adjust slider from channel editor is disabled, if not enabled in [Settings]->[General]
button [Infos] from main window was deleted, all submenu items moved to button [Tools]
option to select filter type in PID recorder window
option to add extra PIDs when start channel recorder (NIT,SDT,EIT,TDT), default values configured from [Settings->Recorder]
option to disable elementary streams sorting after scan (default: sort by kind)
the audio and subtitle PID are preserved when updating the channel, if they are still available after rescan
added [Screenshot], [Mute/UnMute], [Audio] and [Subtitle] selector in the video window context menu
aspect ratio “Auto” based on detected video mediatype
aspect ratio saved per channel
increased maximum number of PIDs allowed into recording slot from 16 to 32
added PID filter type FTS_DAV = Full TS with decrypted audio/video
allow to add transponder with the same frequency,polarity but different decapsulation params (PID,PLP)
allow to save channels with the same frequency,TID and SID but different input stream (MIS)
added ONID (from SDT) to channel identifiers
teletext parser reads the charset from X/28/0 and X/28/4 first triplet, if broadcasted
teletext pages updated correctly if bit C11_MagazineSerial is set
diffs report after channel rescan
new subtitle settings page
subtitles can be enabled/disabled/switched with double-click on channel ES list
subtitle status indicator on the current channel’s ES row:
“Green dot” when first valid subtitle is received
“Red triangle” on error
(see indicator hint for more infos: bitmap size, teletext charset or error message)
new command line parameters:
/DEV ,, – start with specified DVB device, example /DEV Dev_BdaDriver.int,DVBS,1FDC
/MON n – start application on specific monitor n , n > 0
Scanner window:

sorting of transponders list by clicking on columns header (“Sort by” combobox was removed)
new column in TP list to show number of saved channels + hint with the names of first 20 channels.
Satellite edit window:

bugfix: raw command shows incorrect value “00 00 00 ED” when switch type = none.
the text “DISABLED” is now replaced with an empty string.
use configured frequency units (KHz/MHz) for LOF values
TS analyzer:

count lost packets
non-modal window (useful to check discontinuities right after tuning to a new transponder)
data rate changed from KB/sec (KiBytes/sec) to Mbps (MegaBits/sec)
Dev_BdaDriver.int:

bugfix: skip configuring PLS=None on TBS USB devices before tuner initialization
device ID is derived from hardware ID. It should help in cases where you have multiple USB devices and you disconnect one of them. In the previous version the ID was changed because it represented the device index in the BDA enumeration, now it should only change if you change the device USB port or PCI-E slot. If needed, can be reverted to old mode by editing Dev_BdaDriver.cfg
Fixed bugs:

bugfix: uncommitted LNB4-16 reverted to LNB1 when re-edit satellite (link)
bugfix: Channels menu item from tray icon not linked to any action (link)
bugfix: bug related to T2MI, scanning/tunning same frequency & multiple PLP (link)
bugfix: DeliverySys value from channel not passed to tuner request params. (link)
bugfix: the EPG parser stops when closing EPG window even if background parser is enabled in settings
bugfix: in fullscreen mode, the mouse does not hide after 2 seconds of inactivity
bugfix: last channel & last selected satellite were reset after using different device type (DVB-C/T)
bugfix: incorrect draw of teletext doubleWidth/doubleSize characters
bugfix: teletext window cannot be resized from left or top
bugfix: bad position of some windows on multi-monitor system
