[ExtractStream] convert to divx?

[Matthew Barr]

I use tyc on the Mac to do both 2 & 3. It seems to produce nice output,
when used w/ video lan client. I haven't tried the ffmepg stuff.. I
wonder how long it will take to add in support for MPEG-4, w/ AAC?(the tyc source is available, and needed a small patch to compile on the
Mac. I have the binary, and someone here kindly provided the patch to the
source. I can repost it, but someone else definatly did the mental work.)
