As an alternative to what everyone else said I have a 700Mhz Duron and
can playback MPEG2 DVD with about 60~80% CPU use and a SD XviD with
40~50% using xv assistance with mplayer in debian etch, but without
MythTV overhead, so if you could get one of the (usually USB external)
tv cards that record to an XviD type MPEG4 variant, as opposed to an
h264 type, or MPEG2 (for the PVRs) you might not need to upgrade anything.
Alternatively, you could use a PVR150/500 and give it a go watching the
MPEG2 with xv, if that fails upgrade the graphics card to one that can
do XVMC, or if your not in a hurry you could transcode all recordings to
a less demanding codec, then you could probably use your current hardware.
A third option is just to use the Athlon 600 box as a backend and watch
from a more capable frontend.
