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.

What kind of streams are these? What bitrate and resolution?
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.

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 ;)

You can change the A/V offset in xine. I sometimes hit the key by mistake ;-)
Kind regards, Stefan
