Maybe I should have said, audio sync. The audio stream is ahead of the movie stream. I've tried it on each of the "DVD to Movie" profiles and with varied settings, and with different DVDs but each has the same result. If I copy DVD to DVD then all is okay, it's only the "DVD to Mobile". Perhaps if all who read this thread could just indicate whether you've used the "DVD to mobile" feature and whether or not you've had any problems with the audio / video sync. Thanks. Alan
