The PVR500 has 2 tuners running off one cable/antenna input. It has
S-video and composite inputs. The PVR500 has NO video outputs. Each tuner
has hardware encoder/decoder which really takes a load off the CPU.

No S-video out, only S-video in, on the PVR500. The PVR350 has only one
tuner, but it does have S-video out..... Choices choices...

Or a motherboard which has a builtin mpeg hardware decoder such as the
latest VIA motherboards. I have the SP130000 which has both VGA and
S-video out, and has builtin XvMC acceleration.

I record with the PVR500 or the HD3000 card using 720x480 for standard
definition TV. Recording 2 shows at once with the PVR500 gives about 7-10%
load. Playback is about 30%. This motherboard will not likely do HD...I
haven't gotten any HD content, either recorded or to play, to check it
out. I'm not really worried about it at this stage.

Then again VIA has just announced a new motherboard/chipset combo for
release early next year... It is supposed to do HD....using hardware
encode/decode. Maybe I'll buy myself a late christmas present! The present
mb would still make a rather nice fileserver here in the office..or just
replace the Pentium200 which my wife does not use (often) for her email..
