That does help, and is encouraging. Thanks! My specs are pretty similar
except the PCI Video card and single IDE hard drive. The MB is what
came in an HP dc5000mt. I have 1.7GB of DDR400 RAM, and am also running
Gentoo and using .20 ebuild of Myth. I have tried several variations in
the compile, but currently have the following in "packages.use"
media-tv/mythtv mysql lirc dvb video_cards_nvidia nvidia xvmc dvd
opengl opengl-vsync ivtv
My tuner cards are an ATI HD Wonder and a PVR-150.

good HD off a P4 3.2G or less without XVMC?)
I'm running on a p4 3.2 Ghz machine which is running Gentoo Linux and
I've installed Myth using the ebuilds. My machine specs are:
p4 3.2Ghz with hyperthreading enabled
Gigabyte P945 based motherboard
4 x SATA 300 HD.
Gigabyte GeForce 6600 PCI Express VGA
1 x PCHDTV 3000 PCI HD tuner card
1 x PVR-500 PCI SD tuner card
I have no problem playing back HD without XvMC enabled and this is a
combined frontend backend machine. I am currently not displaying at HD
resolutions since I don't (yet) have and HD display, but the machine
is decoding an HD stream.
Hope this helps.
