[QUOTE="offbyone, post: 1006784, member: 73415"] Back to the original question: Not every h.264 stream can be hardware accelerated by every GFx card/driver combination. The hardware accelearation only kicks in, when the file's encoding is fully conforming to the specification the graphics card wants. In case of h.264 there are really many possibilities how you can envoce your video and older graphics card tend to have more tight restriction what they support hardware accelerated. Especially videos used around the web are often expected to be played via flashplayer embedded on a html page, so the creator does not care or comply to some standards in video file encoding. So it is very well possible that many Online Videos are not going to be hardware accelerated, which is why they stutter on lower end systems. [/QUOTE]
