Xvid to DVD - No audio when I try to author to DVD

[gnslinger]

I'm trying to convert an Xvid to DVD. I've done this plenty of times and never had any problems, but this time I'm trouble with the audio. Here's my process: I demux the audio (AC3) using VirtualDubMod, encode the video using AVISynth and CCE, and then author the two together using DVD Lab. But when I go to compile it, it gives me the error 'Cannot packetize audio stream'. It will still finish compiling it, but I get no audio with the finished product. I tried using DVD Author, but it wouldn't even compile it at all. Any idea what's causing this?

Sounds like an error in the audio stream.

Try running it through ac3fix.exe before authoring.

Yup, that fixed it. I always thought you only had to run it when you were combining to Xvids together. Thanks for the help.
