I can also confirm that this is a problem with my late 2006 MacBook Pro, 
running 10.6.8 in 64-bit mode. I had been using Quartz in 0.24 
(self-compiled) with no problems decoding or playing 1080i MKV content 
from a HDPVR. I don't recall what profile I was using, but I'll check 
when I get home.

I haven't yet tried the VDA profiles in 0.25, but OpenGL High Quality 
and "Normal" stutter so badly as to be unusable.
