Video and Audio out of sync

I burned 8 mpeg2 video files in DVD-Video format, here are a few questions:

Why does the files still need to be converted since it is already in mpeg2?

The video and audio are sometimes out of sync, how can I prevent that?

What input format has the shortest converting time?

(My video files were originally in rm format, i converted them using WinAVI)

In general if it's exactly in the DVD format, it does not need to be converted. (And, re-coding an MPEG file will degrade the video quality.) I'm not sure how Movie Factory handles compliant files, but if you're not changing the bitrate or the already-multiplexed audio format, all movie factory has to do is create the AUDIO_TS & VIDEO_TS folders and break the file into .VOB files.

Search the forum for "sync" and you'll find lots of suggestions & possible solutions.

When it happend to me, it was caused by corrupted files. The corruption didn't show-up 'till the files were "converted" or re-multiplexed. And, MPEG files can be corrupted simply by editing them!
