Does Nvidia driver support 7600GS features?
 
I'm in the midst of assembling components for building a MythTV frontend (on Ubuntu 6.10). My question relates to the specialize HW on the XFX 7600GS video card. Does the drivers available from Nvidia support the High-Definition H.264, MPEG-2 and WMV hardware and integrated HDTV encoder on this card? Or is it largely ignored?

Also, I can't seem to find the maximum resolution available from the S-video connector on any spec sheet. Is it 1024x768 like other Geforce4 tv-out processors or is it 1080i as listed for the integrated HDTV encoder?

Thanks for any enlightenment.

The linux driveronly offers functionality for mpeg1/mpeg2 decoding using XvMC which is supported by most players. Second s-video isn't made for very high resolutions. In general a HDTV is connected using component which offers better image quality and higher resolutions than s-video. The best thing to use is ofcourse DVI/HDMI.

Thank you for your reply.

I guess this means that the card does not offer any HW assistance to decode MPEG2 streams and offload the CPU. Pity.

My current AV setup precludes the use of component, DVI or HDMI interconnects because of limitations in the AV receiver. So, S-video is the only interconnect I can use at the moment until I upgrade major components in the system.

My research reveals that low-end Nvidia Geforce4 cards support 1024x768 max. resolution from the S-video connector which will match well with my current SD video setup. And I suspect the same S-video driver hardware is probably being used in the 7600GS. So it makes no difference, from the perspective of video performance or supporting my current interconnect setup, if I invest in a video card like the 5200 or a 7600GS Nvidia card. However, if I plan to upgrade to HD one day, getting the 7600GS would be the best investment today (and hope for HW supprt in the Linux driver in time). Is this a correct analysis?
