I tried your patch last night, built the latest SVN version, and I was
able to get video on my Mini.   This is a big step forward!

On my system, displaying HD video took more than 100% of one CPU.  
So, playback was a bit choppy.    I'll try to throw Apple's profiler
on it, and see where the major cpu drains are.
