audio sync problems driving me crazy
This is driving me crazy. I'm burning DVDs from captured MPEG files. These are movies analog captured from a Scientific Atlanta Explorer 8000 DVR-Cable Box. The MPEG files play perfectly in 3 or 4 different file players. When I process and burn the files (to HD VOB files/folders, or to DVD--tried different brands and formats), I get sometimes (not always) audio sync problems. This has happened with both Roxio 6 and Nero 6 authoring programs. When it happens, it happens with both.
There are two cases: The first I think it relatively simple: The audio is out of sync from the outset.
In the second case, the audio goes out of sync at a certain point in the playback where there's a "jitter" in the video, and is then out of sync for the rest of the playback. (Dropped frames? but don't forget: Not in the MPEG source file, and in the same spot in the output from two different programs.)
I'm a relatively sophisticated computer user, but new to this video/DVD stuff. I have a computer I built myself, running WinXPPro on a 500 Mhz P4 with plenty of RAM and HD space, ATI 128AIW video.
I have googled "audio sync" and looked at many results, but none addressed my problems directly. I have downloaded the various shareware that I found mentioned on forums: VOBEdit, VDubMod, TMPGEnc, IMGTool, DVDShrink, DVDDecrypter. I can't find any way to work on this. I was hoping they would provide a way to solve the problem if it was introduced by other software. I would think, for example that VOBEdit might help me. It gives the audio delay (which might be the only problem from case 1), but I don't see how to change the value.
I'd be grateful for any suggestions. At the least, I need to know how to explore and change the audio sync in DVD/VOB files.
Thanks
