My dual core AMD Athlon 64 4200+ with 2Gb RAM, Gentoo, Geforce 7600GS
NVidia graphics card running just as a frontend (backend is over a 100Mb
LAN) using the nvidia binary drivers will just about play it. It has
the occasional glitch but nothing major.
I'm running the latest 0.21.xxx Mythtv (not svn). I had to fiddle
around with the playback profiles a bit to make it work. I changed my
settings to just have one playback profile (so I could be sure which on
was getting used!) that uses the standard decoder, 2 CPUS, xv-blit and
the softblend osd renderer.
I find that if I have anything else running, even de-niced processes (I
normally have boinc running) then it can't cope.
