The processing in the GPU for HD-DVD and BluRay is not really post-processing. It is H/W acceleration of the decoding that it required. VC-1, AVC, h.264, etc are all very compute intensive for both encoding and decoding.

Once you have an actual 1080p frame the GPU can very easily scale it, sharpen it, etc. Those functions are all hardcoded into the video pipeline.
