NVIDIA beat AMD to the punch with their full H.264 decode acceleration on G86/G84. Of course, AMD is one upping NVIDIA this time around, as their UVD (Unified Video Decode) architecture is also capable of decoding VLC bitstreams on all three HD media codecs. This means that there are no cases where AMD hardware will not handle 100% of the video decode process (after the CPU has dealt with pulling the encrypted content off the disk and preparing it to send to the GPU that is).
