The problem is that it is hard to get full quality decoders in
realtime with limited power, area and money budget. Thus engineers
tend to comprimise at some points, trying to simplify the problem
by allowing the system to act inacurate. How bad these approximations
are is most time not clear until customers complain.

Where do you see hardware motion compensation? The TMS320DM6467
looks to me just like a VLIW DSP combined with an ARM chip and
a lot of peripherial stuff. No fancy decoder unit.
BTW: What is a hardware motion compensation for you? I ask because
the process of motion compensation is something that looks always very
similar, no matter how much you do in hardware.
