Question: How to get an AVI file burnt to DVD with proper audio sync?

Ok, my google-fu has failed me. I'm trying to find a simple software program that will allow me to take an AVI file (or multiple AVI files - TV shows, mostly) and burn them to a DVD-R while still having the audio sync up properly. I've tried a couple of programs, and for some reason, the audio ends up being out of sync toward the end, although it's just fine at the beginning.

I use to convert my files from avi to svcd(plays on most dvd player) w/ a program called DVD2SVCD

But then I bought a new DVD playerfor $57 Philip's slimline from walmart that plays Divix avi's straight off a cd for television programs, much less of a hassle worth every penny!!

There is far more help than you could ever want on these matters on VCDHelp.com, even little search options to specify you want to go from X to Y format.

Short version: using virtualdub, you need to decompress the audio to a separate .WAV file, and then recompress it while doing a straight copy of the video to a new file. It takes about ten minutes total on a 2.4 GHz P4. This will prevent the skew from being introduced into the file.

Do you need step by step instructions?

I've tried some of the programs mentioned at vcdhelp.com, but the audio is still 'skewed' on the DVD output. I suppose the problem is with the source files rather than the conversion program... hmm...

sun-el: I read your comment and had the deer-in-headlights look, so I'll probably say yes, step-by-step instructions would be good. :-)

Diko is a one-click DivX to DVD conversion tool. It's worked on every avi I've given it. Free.

The problem you are experiencing usually has to do with the endonding scheme that the AVI was created with. It is most likely Divx/XviD with a VBR (variable bit rate) Audio Track. Transcoding a VBR file almost always results in the audio getting out of synch(at least in my experience)

sun-el is on target... you need to use a modified version of virtualdub (named virtualdub-mp3freeze) to convert the whole shebang to a format that does *not* use variable encoding on the audio track.

(I keep a scratch disk with at least 80 gig free, so I personally just have it save the video and audio uncompressed-- this tend to make GINORMOUS FILES however-- it's about 37gig for a 45 minute show-I do this to keep from degrading the video any more-- each time you convert to a different format, you are likely to lose quality)

Depending on the speed of your computer, the conversion to MPEG-2 should take about an hour and a half for your typical 1 hour show sans commercials. From there you can use pretty much any authoring software to make the disc.
