hi Michael,

  Thanks for pointing me of the issue. However, I think the detection
should be trivial since there are few corresponding accelerated
implementations for idct and motion compensation in libmpeg2.

Ought to enumeration all possibility or not, I am wondering, and I
appreciate the discussion in MPlayer mailing-list.

Sincerely,
