On chips without UVD, video decode was done using the 3D engine which pretty much limited it to MPEG2. It was basically just MC offload. R3xx-R5xx had robust enough shader ISAs to implement MC offload directly. R1xx and R2xx chips had a special MC mode you could enable in the 3D engine to accelerate MC offload.
