@Pinkeye.....is this a TV show DVD..... like season 1 disk 1 that has 8 or 9 shows on it? I use DVDDecrypter, then DVDRemake to take out all the unwanted stuff.... then use DVDRebuilder Pro/CCE/or ProCoder2 then burn with CopyToDVD after testing out the movie folder! Comes out great! I did ER, Doogie Howeser, NYPD Blue, Desperate Housewives, House, Married with Children.... all first seasons and some second season, all came out great this way. the only one I had a problem with quality was Doogie Howser,MD... but that was because the source DVD was crap to begin with (was not remasted, show was in 1989).
The movie files are XviD with AC3 audio, and i've been using a combination of avi2dvd and dvdshrink, but have not yet learnt how to burn multiple files onto a dvd that weren't two parts of a movie(e.g. CD1,CD2).
