Stephen,

I've never found a way to control the audio format & compression while using the video grabber. One thing I'm going to try this summer is using a shell call the unix utilituy ffmpeg to post-compress video and audio after the initial capture. I'll let the list know if I succeed in getting it to work.

Devin
