Our theoretical article about ATI AVIVO technologies had been published long ago. But we had no time to test hardware accelerated video playback. It had to do with the fact that both ATI and NVIDIA were developing support for video decoding in drivers so actively, that nearly each release introduced lots of new features. So it was difficult to compare GPU performance, as the situation would change every month. And now everything seems to settle down a bit. Either ATI and NVIDIA fine tuned their support for video decoding, mentioned in our theoretical article, or they just grew tired of this task. So we decided to analyze the situation with hardware accelerated video decompression and playback.
