tested the beta driver
- platform ASUS P5N7A-VM (GeForce 9300, nForce 730i)
- mythbuntu 9.10. kernel 2.6.31.x-386 (packaged kernel)
- Technisat CableStar HD2 DVB-C tuner card
- 4GB RAM, GPU using 0.5 GB
- Core 2 Duo Conroe E2140, 2 x 1.6 GHz, overclocked at 2.1 GHz
HD TV stuff with mythtv 0.22 is smooth with vdpau (using normal deinterlacer, not advanced but that did not seem to matter), CPU remains at ~ 5 %.
mplayer works fine too, CPU ~ 2/3 %
so far so good
I have issues with resuming from S3 though but it's not nvidia related (mobo stuff).
I have not tested sound through HDMI though. Should do it at some point.
