I'm trying to burn some AVI files to DVD using WinAVI 7.1 and burn them with Nero 6.6. I normally have no problems but this one batch of AVI files has been causing problems, they play fine in AVI format in Windows Media Player. Once they're converted and burned though in one section the audio is out of sync with the video for a while. And the picture gets all scrambled in some spots and occasionally freezes. I've tried encoding them several times and burning them several times using good quality Verbatim DVD discs but have problems each time. My burner is a Sony DW-Q28A and the AVI files are about 21 minutes each (6 total) and using the Divx video codec, 352 x 240, 29.97fps and a bit rate of 577kbs. The audio bitrate is 56Kbs. I'm not sure if the problem is in the encoding or burning. I've burned many other discs without problem.

Thanks.
