The thing is I'm working with 100% non-Microsoft tools and hardware  
(exception being the XBox and XBox 360). I'm aware of the first party  
support for XviD and AC3 in an AVI container, but the sad fact is that  
my system is rather old, and unless I could hijack one or two cores  
out of the 360 for transcoding duty, I'd likely be at this for weeks.  
Thanks for the advice, though.

P.S. Before you consider mentioning using VLC to do a real-time  
transcode, I ought to forewarn you that my 1 GHz PPC doesn't have  
enough pull to decode these videos in real-time, let alone encode to  
XviD in real-time. Just trying to let you know what options I'm aware  
of and have explored.
