Hmmm....  I may be wrong about this, but from what I have heard and read,
the Radeon's MPEG2 encoding on the fly ability is what one might call
"hardware
assisted" (ie - a piece of hardware on the card does the more difficult
sections
and the Windows software does the rest).  I have a Radeon in my PC at home
(a Pentium II 400), and I am able to encode full frame rate 640x480 with
very
few dropped frames.  However, my experience with software encoders on
my work test machine (a loaded PIII 1 GHz) is that I can only get 2 or 3
frames a second at the most at 640x480.

This indication would help confirm my previous thoughts on the Radeon
having "hardware assisted" compression...  I will try to find some more
information if anyone is interested....
