Power to run mpeg-4(h264)?

[gimme dvb]

I've got an Athlon XP 3200+ with 2gigs of DDR memory. My card (Geforce 6600GT) I think is too slow to run h.264. I've already tried all combinations of codecs and the video is choppy. Do I need a faster card to let me run h.264 without problems or do I also need a faster processor?

I tried a 2.4 P4 and it would not get the job done either even overclocked to 3.0. Assume the CPU is at 100%? Did you use coreavc and intervideo? Sounds like it is time for an upgrade to a dual core & DDR2 and an Nvidia 8600GTS. Only the 8500 and 8600 cards do hardware H264 GPU accel. Cyberlink is the only codec that works well with GPU accel. My second machine below gets the H264 job done overclocked with a single core but with the onboard video it is heavily tasked. An add on PCIE video card would make it work better.

I've read somewhere processor should be at least 3000+ for reproducing HDTV.
I don't know if can help but I've read new radeon like 2400 and above should have mpeg2, divx and H.264 hardware acceleration.
Pehaps it also help in viewing HDTV by a DVB-S2 tuner, but I don't know.

Well I can run h.264 movies fine on my pc. Running them with dvbdream is a different thing, seems you need more power.

Aah..., perhaps it depends also by the dvb-s2 card and the program you use with it. For example using some other dvb program I noticed a low consumption of processor power but when I use my cam it ask a bit more "power" request and if you use a software cam things goes worse.
What I mean is that perhaps with new realase of DD things could go better because pehaps with new DD version rel optimize the code.
I' m not sure of this because I have already a low cpu usage on SD channel.
In any way with your PC configuration the thing with less performance is the cpu. I don't know what socket you use but if you use a AM2 socket you can choose every x2 processor you want from 4400+ and above, they don't cost a lot. If you have a 939 socket you can consider upgrade to 4200+ or opteron 175 or above as I did. The opteron cost a bit more but it have more l2 cache. If you want a big upgrade 300 euro, intel Q6600 and a motherboard from asusteck or asusrock that read normal ddr could give great performance.
But the point is that perhaps it couldn't help that much.
Hoping havn't confused you

Playing back verses demod/decode/rendering H.264 are two different things. Most modern PCs can playback H.264 with PDVD or Intervideo. The CPU/GPU challenge comes when decoding and rendering demodulated DVB-S H.264.

DVB-S H.264 demodulation, decoding and rendering require CPU/GPU horsepower.

Thank you for the precisation, now you let me think about it, it make sense
But the point is what configuration of cpu/gpu is powered enought
And then consider the codecs
