I just grabbed the latest 0.21-fixes from svn, and it is now displaying fine.
I guess my previous version must have been one from early in the release cycle.

I built it via osx-packager.pl,  and it didn't require any special
patching to get MMX working.  I'm using the latest iPhone SDK,  gcc
version 4.0.1 (Apple Computer, Inc. build 5250).    With this build,
my CPU usage is as low as ever.  With previous builds
 I struggled to get the same performance as with 0.20.   Now, I can do
1080i HD playback with commflag running on my Core Duo 1.66GHz Mini.
