I have been ripping my DVDs to .avi to watch them while on my treadmill using my Cowon A2. I have been using DVD Decrypter to decrypt them and AutoGK to shrink them. Recently more and more of the DVDs are having audio sync problems. Is there anything I can do with those programs to avoid the issues? Are there other programs that will work better? Which program is really causing the problem, DVDD or AutoGK? Any insight would be appreciated.
