[M4IF Technotes] Direct Mode & Qpel interpolation

[Liron Ain-Kedem]

Hi,
It says in section "7.6.9.5.3 Generation of prediction blocks" (for Direct
Mode) that:
"Motion compensation for luminance is performed individually on 8x8 blocks
to generate a macroblock."
But I found no evidence of that in the reference code - on the contrary -
Motion Compensation is done on a complete MB (even in quarter_sample mode)
and NOT on 8x8 blocks.
Can anyone help?
What should be done - MC on 4x 8x8 blocks or on a whole MB - 16x16?
Thanks,
Liron
