desired size/quality?   My p4 2.4/533 can do 3500kbps 640x480 with the
high-quality option enabled...  Uses about 70-80% of the CPU, but I
don't use myth for live tv, so it doesn't matter to me.  So with that
system, you could probably easily get away with 480x480 at a lower
bitrate.

You could also just use a nice HQ rtjpeg and then transcode to mpeg4
later.
