At the moment I am experimenting with HDTV on my Pioneer PDP435XDE. I can receive all the test broadcasts via Astra(s) and Hotbird. I use vdr-xine on an Athlon 3000+ (2.3Ghz), 512Mb RAM, Skystar2 and a Nvidia MX440 using X11 at 720p. The picture is perfect and perfectly smooth. Unfortunately I cannot receive the DVB-S2 MPEG4 broadcast of the SKY UK HD demo at 28.2 degrees East.
how much cpu is used with this setup?
I'am almost certain, that no matter how much cpu power you have, there will always be audio/video glitches with software decoding under certain circumstances - high i/o-load, other processes running etc. (a friend of mine has such a ultra-mega-high-end-system running XP but didn't hear and bought just a budget card - he must run the system completly unloaded to be able to watch TV, otherwise all sorts of glitches apear)
Remember - linux still hasn't realtime scheduling for multimedia purposes included, KURT was once the right way to go, IMHO, but it didn't made it.
##A dedicated hardware decoder is therefore really useful for undisturbed watching.##
Besides you can use a much less power hungry system and still have some cycles to make your box more than a media-center - mine is used as a workstation at the same time, doing email, internet, programming etc.
