Hello,
I know 720p, 1080p/i resolution are getting common which is fine.
From the next feature thread I see there is some interest in H.264
channels :-)
I don't like the hardware decoder solution : Intel core duo 2 are really cheap now and don't use that much power...
I built my VDR PC (in fact my only PC...) with such a solution (and a fanless nvidia gfx card) and I find it perfectly suited for HD. The most important part from my point of view was the case : http://techgage.com/article/antec_p182_performance_mid-tower/
So that I don't have noise from the PC...
I think almost any PC with core duo 2 CPU are enough for perfect H.264 decoding...
I don't really like closed hardware solution neither...

I have CPU: Intel(R) Core(TM)2 CPU 6400 @ 2.13GHz (Family: 6, Model: 15, Stepping: 6) and picture of "x264 recording VIDEO: [avc1] 1280x720 24bpp 23.976 fps" is just perfect, but sound comes out about 0,2 second too early with xine.
With my other machine "AMD Athlon(tm) 64 Processor 3400+" can not play those file with-out heavy problems, totaly under power CPU for that kind of playback.

My friend has a configuration
hard: Asus P35 + Intel 2160 @ 3GHz + 2GB ram (@800MHz) + SATA disk + ATI2600XT 256MB + TT3200 soft: debian testing (lenny) kernel 2.6.22-2-686 V4L-dvb = Multiproto - 26.10.07 xorg video driver = ati 8.41.7 (fglrx)
vdr 1.5.10 + vdr-1.5.10-dvbs2-h264-syncearly-framespersec.diff xine-0.8.0 plugin
ffmpeg-cvs from 08.11.2007 xine-lib-1.2 from 8.11.07 xine-ui from 8.11.07
and can see the h.264 dvb-s2 channels with average 60% CPU load.

For real comparisons we will need to specify the exact stream parameters. If sombody has some links to files, I can run tests on a decypher chip. Then we can compare that to the load on different CPUs.

What kind of streams are these? What bitrate and resolution?
Astra 19,2E, the channel - Discovery HD, it has the largest bitrate from known - Min-Avg-Max kBit/s 8265-15597-20175 the current bitrate you can find here http://www.linowsat.de/0192/24h/6/130.html resolution - 1920x1080
yes , it's very useful

i would really like to see this - allthough i can't help in finding files. Even a C2D + RAM +Video card @60% load for average TV viewing sounds crazy to me - so i would prefer HDe as well - as soon as it is available and some people are using it. At the moment with my CRT TV there is no real use for it anyway ;)
