Not FC5 but Ubuntu Dapper with a single core Athlon 64 3500+ at 32bit.
Same setup as above with video card and driver. Both can play HD
content using Bob 2X. I had some problems with HD playback (stuttering,
NVP pauses) that appears to have been resolved by tweaking the modeline
for X. I can play 1080i content without XvMC at around 60%. Strangely
enough XvMC increases using to about 80% so I've disabled it for now.
To get to this point I basically hooked up a Windows box running
Powerstrip, used EDID to setup a proper 1080i resolution for my Hitachi
Plasma, and transferred that modeline to X. In order to get it to work
I had to disable both horizontal and vertical refresh check (see Nvidia
readme Options) as X was rejecting them as valid despite what the EDID
for the plasma was reporting. This did the trick.
