XvMC (MPEG-2) HD:

^^ These guys posting their rigs and success of hd playback with mpeg-2 only not more advanced codecs.
It seems like the goal of XBMC Linux obviously is to play our favourite h.264 rips or xvid (probably not mpeg-2).
As i understand, the nvidia drivers barely support mpeg-2 in linux and doubtfully any h.264 or xvid?
I had to use the newest nvidia kernel (Envy built) to get my 8600 GT OC to work. I am starting to wonder if my boxen (1.8 core 2 duo, dual interleaved ram, sata II 300 ncq, 8600 GT OC) is going to be able to handle the raw power to play (audio/video/hardware overlay?) the popular formats.
Perhaps their info is old? Has anyone run some hardcore benchmarks on their systems showing 1920x1080p,1080i, 720P codec (x264/h264/xvid) using the player we are using to see if we're going to be happy with the results? Mpeg-2 is unreasonable due to size and the fact transcoding would suck time wise.
I think alot of people are here because HR-HDTV isn't cutting it any more and their xbox1 just can't handle high def playback.
What do you guys think? Thats why i'm here and i'd be glad to help but it would suck butt to build a whole machine only to find out our favourite formats and formats to come (let's assume 1080p h.264 in the next couple of years) are realistic.
I guess we'll need to rip some HD-DVD to h.264 (or free equivalent) and play it back at 720p and 1080p and see what kind of results or quirks we are getting.
Almost makes you wonder if vista using all the fancy video enhancements for nvidia G84(8xxx) or ATI would be an easier (money wise) platform.
Also i noticed the x64 seems to be used alot with MythTv and it enhances performance greatly. Getting things to run x64 probably way too far ahead at this time but if you just took our video player on such a platform we could compare the advantages (if any)?
I guess my fallback if the goals aren't realistic at this time would be a transcoding box that uses high bandwidth and low compression to feed the xbox1 high definition playback offloading the nasty cpu to a backend server?
I'm not savvy on all this high def stuff but perhaps someone could put together a benchmark many of us could test to see what kind of CPU load is needed to PASS/FAIL playing the modern formats? or perhaps that might just be some public domain videos we can encode and hand out here to give to others to see where their hardware stands.
If i'm way off base just tell me so but i do respect alot of the mythtv folks for already having figured out what sound card works (digital 100%) and sticking to nvidia for driver support.
Any thoughts?
