U tome pdfu je napisano koje grafe imaju h264 akceleraciju.. mnoge imaju..
ali da bi vrsilo akceleraciju materijala sa dvb-t tunera, treba ovo :
H.264 Decode Acceleration with IDCT and CAVLC/CABAC
e to imaju samo par njih, 8800gt to nema :/
edit : mozda ono tvoje gore stoji, mozda ova izjava nvidie govori samo za 8800gts i gtx :
Q. Do the GeForce 8800 series GPUs include the same video processing capabilities as the new GeForce 8400, GeForce 8500 and GeForce 8600 GPUs? No. The GeForce 8800 uses the previous generation of PureVideo HD. This is because the GeForce 8800 is usually paired with more powerful dual-core CPUs and our goal is to achieve balanced use of all the processing power in your machine. With the GeForce 8800, it makes sense to let these powerful CPU cores handle functions they do well. But with the lower-end GPUs, which are usually paired with less-powerful, single-core CPUs, it is better for the GPU to take on the entire video decoding and processing task and the new PureVideo HD engine has been enhanced with these chips in mind.
