Gotcha, software encoding is definitely different from hardware
encoding. At least a Athlon XP 1900 is only around $72 right now. For
now I have a spare 1ghz tbird sitting around.
Now when you refer to 2 full size encodings, do you mean recording one
channel in background and watching live tv in another? Or do you mean
recording 2 channels and doing nothing on the tv? Or perhaps another
option?
Any plans to create a self contained distribution CD, almost like some
of gentoo's live cd for unreal tourn 2k3?

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.
