OK, OK I think I've got it sussed. I had to enable full stream audio processing in virtualdub to get it to sync the audio when it converted it to 24fps. I have no idea whether this is what made the difference but I have converted two previously unworking videos to have perfectly synced audio.

So here is the list of things I do to a wmv.

Once through Xilisoft MP4 Converter 3 to make it an AVI
Once through VirtualDub to convert it to 24FPS
Once through AvConverter 1.0 Presumably Giving It MP2 Audio

Anyways that sequence seems to work so I'm happy

Thanks to the guys who helped me figure this out.
