I have used many SVN versions, form a few months before 0.20 release
until building a new version a few weeks ago.   The pre-0.20 stuff was
taking almost 100% of my CPU.  When MMX enhanced colorspace conversion
was added with 0.20, I got quite a bit of CPU headroom.

I just run the plain vanilla build generated with osx-packager.pl (if
you have XCode installed.  See
http://www.mythtv.org/wiki/index.php/Myth_on_Mac_x86 )

Is your display output 1080P?

How does CPU utilization look in 'top' while playing 1080i?   The
"Shark" tool with XCode gives good information about where CPU is
being used, if you find your CPU is pegged.
