I've burned a handful of movies and they all seem to have occasional skipping in them. It wasn't a real problem until "I, Robot". I tried watching it last night and it froze and skipped like crazy. It even occasionally skipped entire chapters. Is there something I can do to fix the problem? I'm usind DVD Decrypter and DVD Shrink and burning at 4X. Maybe I should burn slower? I'm at a loss and a little dumb about this whole thing, please help.
