<g> It is useful for people who do not have Pentium 9 with 50 THz clock and 
ExtraMMX7ProExtended, with 512 TB RAM and 3000 kW power supply. <g>

To be serious, I think that manfacturers of graphics chips and programmers of 
well known DVD players for windows  would not waste time for implementing 
hardware acceleration of idct and mc if  it was redundant. Hardware 
acceleration of idct and mc can save procesing power of CPU which can br used 
for e.g. DTS or AC3 decoding, picture post-processing, to lower power 
consumption. IDCT and MC steals 60% of processing power of CPU that is why it 
is accelerated by graphics chip. I know from radeon driver programmers that 
writing idct and mc acceleration driver is very, very difficult. So I think 
that in the future someone will face this task.
