Linux Efforts to implement NVIDIA's Video Decode and Presentation API for Unix (VDPAU) on the open source Radeon Gallium3D drivers (for AMD/ATI chipsets) are reportedly just beginning to work. Being Gallium3D-based means this new VDPAU state tracker is using GPU shaders and not the dedicated Unified Video Decoding (UVD) engine found on modern Radeon HD graphics processors, but using shaders is still a big performance win for HD video playback compared to pegging the CPU constantly. Also, MPEG-2 is the only codec known to work at this time. Once the basic state tracker functionality works, support for other video codecs, such as VP8 and H264, should be relatively easy to add.

They where "slow" just as much because of old school fixed function GPUs as they where because every company had to reinvent the wheel by coming up with their own proprietary method of doing the same thing that did nothing but case massive compatibility problems with accelerated apps and games back in the bad old days.

These days with unified shaders they can implement allot more features allot faster, hence the *.1 releases backporting new features to older GPUs that can still handle the new extensions.
