This is the 3rd post I have posted on the following: I have been using AVI2DVD and DVD Decrypter for a few years now and for some reason the last 8 movies I have converted are faulty. I am using the latest avi2dvd version and the same with avi synth. What actually happens, when you play the dvd on the DVD Player you can see the people talking, but the words are either being spoken earlier or later then when the people in the movie are saying it. I know this sounds strange, but if I could use an example as, saying the word hello. Sometimes the actor in the movie will mouth the words hello, then a few nanoseconds later the words would be spoken, and sometimes the words are spoken, but the mouthed words need to catch up. I know this is confusing, it is for me, but this is a real problem and I can't work out what to do to fix it. I have tried to delete and reinstall all 3 programs, avi2dvd, avi synth and dvd decrypter, but the problem still persists. Can anyone help me with this problem so I can get descent working movies again. Thank you for putting up with my confusing problem. Take Care. For once I would like to post a question here and get an answer within a ONE MONTH period, I thought these boards where here to help people and not waste their time. This happens to be the slowest forum I have ever seen in my life, if I knew of a different forum that dealt with AVI2DVD I would go there.
