In theory the 3D engine could be used to aid in the video decode process, however none of this has been implemented yet for radeon hw. The 3D engine can also be used for video rendering using the texture engine and this is implemented for r1xx-r5xx radeons. for decode, the 3D is generally used for motion compensation (MC). r1xx-r6xx radeons also have dedicated idct hw. On newer chips the UVD block handles all of this. There is work going on to support XvMC decode via the 3D engine using gallium, but that will need gallium driver for radeon.
