Ok, so now that my prior question was answered (pvr 350 won't decode
hdtv stream from hd5000), I'm moving on to the next logical step.
I'm trying to avoid having to upgrade to better hardware but I do
realize that it may be the best solution.
So I have a PIII 800 in an abit se-6 motherboard, with a hd5000 air2pc
tuner and gforce 440mx video card. I installed the latest knoppmyth
which supports the hd5000. Right now, I'm just displaying on the
monitor. The goal is to display on a standard tv soon and eventually
an hdtv in the distant future.
The regular def digital stations seem to play with just a minor
stutter. Annoying but I can live with it. The hdtv channels stutter
terribly and eventually lock up. I thought that maybe switching to a
geforce 5600fx would help. It seemed to make no difference.
So the question is, can I tweak some things to make the hdtv channels
play better? I keep reading how the Nvidia cards have hardware mpeg
decoding (which I was hoping my pvr 350 was going to do). It seems
like the nvidia card should do almost all of the work. My little pIII
should not have to do much. How can I tell if the nvidia card is
really doing the heavy lifting or not?

See the section HDTV. I realize that you're not displaying the video in
high definition, but--assuming you have Xv configured--the video card
does the scaling basically for free, so there's real performance benefit
to displaying on an SDTV (so you need the same equipment you would if
you were displaying it on an HDTV).
