I really depends on the recording resolution/quality. I have a backend that
is a P2-333 and a frontend that is a Celeron 433 and I don't have any
problems. I am however recording all my stuff at 352x240. I have a 20" tv,
so better resolutions just don't help, they just eat Hard Drive.
You will probably want more memory though. Add another 128, and you'll be
With a low spec machine, you REALLY need hardware encoding. I wouldn't bother
doing software unless you have a very zippy box.
If you plan an on transcoding to mpeg4, don't spend the extra money on a
pvr-350. It only decodes mpeg2. 350's are also annoying if you want a
separate frontend/backend. If you rely on the hardware decoding, you need
one for each box.
If you are a real sucker for punishment, you could try to find a Rainbow
Runner G to go with that G400 of yours. Its what I use in my backend, and it
encodes in hardware making really HUGE mjpeg files that have to be transcoded
before they are watched. Even a Athlon XP 2000+ frontend can't decode the
mjpeg files to watch them smoothly, thus I can't do livetv. Its is also an
incredible pain to set up correctly.
