I used ConvertXtoDVD and ConvertXtoDVD3 to convert an H264 file to DVD format. It converted fine except that at about 40 minutes it goes out of sync. for about 10-12 minutes and then goes back into sync till the end. The scource is perfect no sync problems. Anyone got any ideas how to fix this. The whole video is about an hour thirty nine minutes. I tried splitting, converting to AVI,ect. and the quality loss is incredible. The DVD is great except for the sync. issue. Help!
