You don't need anywhere near a p4 2.4 for this.  The XP 1800+ I have is plenty 
for really good quality 640x480 mpeg4 video, with lots (>30%) of cpu to 
spare.  That's almost a gigahertz less if you compare straight speeds with a 
p4 2.4ghz.  Now, if you want to do _two_ full-size encodings at once, that's 
a different matter.

TiVos do all their encoding and decoding in hardware -- this stuff is all 
software, unless you use the (still in-progress) hardware mjpeg encoding 
support that's in CVS.
