to get good transcoding result (good quality) i use InstantCopy 7.1.1 (look for test results here: http://www.cdfreaks.com/article/114 ) Disadvantage of IC is that you can't leave the menu's out
So this is the method I thought up. Please tell me what you think:
First decrypt DVD (with AnyDVD or DVDDecrypter, you know the drill...)
Then use DVDShrink and click " re-author". Use only the main movie, usually one file. And use "no compression" this is important. You can leave out the soundtracks and subtitles that you do not want.
Then click back-up, the back-up will usually be bigger than 4.3GB, that's ok!
When DVDShrink is ready, you have a movie-only DVD.
Then startup IC 7.1.1 and use this movie-only DVD as "source". The bit of transcoding that is needed to fit on 1 DVD is done by InstantCopy (best transcoding engine!)
The result is a movie-only DVD with very good quality.
