Before the inclusion of closed captioning retention in 3.1.5, I was torn between CloneDVD, which has retains closed captioning and now can completely remove a title instead of replacing it with a big "blank" file.
However, DVD Shrink QUALITY with the "Deep Analysis" mode in 3.0 beta 5 and higher beat CloneDVD hands down! So, if I had a long (2.5 hours or more) that I wanted to backup, I used DVD Shrink to get acceptable quality. CloneDVD simply butchered the output, which DVD Shrink's deep analysis mode analyzes EVERY FRAME to determine optimal "compression." This seems to eliminate the artifacting in dark scenes and other glitches that CloneDVD seems to introduce at high compression levels.
The user that posted that this cannot compare to CloneDVD must be talking about title removal, which is a shortcoming of DVD Shrink. When doing a full backup with menus, one can strip audio streams (which DVD Shrink does a better job of also), but titles can only be reduced to "still pictures," which results in large useless VOBs using valuable space. The DVD Shrink author coded the newest version of Nero Recode and did adopt the old CloneDVD method of using a blank color to yield a smaller file, but that now does not compare to the latest CloneDVD's complete removal of the title. Luckily if you use the custom output size in DVD Shrink to oversize the output, allow it to create the big dummy files, you can then replace the dummy files with small dummy .VOB, .IFO and .BUP files, and use IFOEdit to "Get VTS sectors," and MenuEdit to remove the menu links to the removed titles. Then you have the best quality AND title removal. The only purpose of replacing the removed titles with dummy files of the same duration was to prevent compatability problems when selecting them from the menu....so, make sure they are not selectable from the menu!
DVD Shrink is the ONLY way to go now that it retains closed captioning. The CloneDVD author claims he will have a version 2 that will surpass DVD Shrink quality with little impact on the speed of the current CloneDVD. Hmmmm, if he's not going to analyze every frame like DVD Shrink, I DOUBT that!
