That's what was happening on mine. Everything played terribly. I had to go into the playback settings and change the video scale option.

I had to change them to a non "0" value, for example, -25%, and then the video was "properly" shrunk to a small size (lots of black around the edges), then, when I set the values back to 0, the video was scaled properly. Very strange, but after that, everything worked great.
Dave, just to be clear, you mean:
Utilities/Setup -> Setup -> TV Settings -> Playback (Page 2/10)
and change both Vertical Scaling and Horizontal Scaling? I know I've tried this before but when I can pry the kids away from the Wii, I'm going to have another go.
I've never had as good playback with .21-fixes as I had with .20.2. I have two Mac Minis running OS X for Myth. The frontend/backend is connected a Sony LCD projection set and to an A/V receiver using digital audio. The other mini is a frontend only connected to a computer monitor and using analog audio. For a description of the problems on the frontend/backend, see:

Todd Ignasiak posted earlier that he had good success with:
Decoder: Standard
Video renderer: quartz-blit
OSD Renderer: softblend
What deinterlacers are you using (primary/secondary)?
While I'm at it, here are the Mac specific settings (pages 9/10 of the above group):
Enable gamma correction for video: Off
Scale video as necessary: On
Frames to skip in fullscreen mode: 0
Video in main window: On
Frames to skip: 0
Opacity: 100
Video in floating window: Off
Video on the dock: Off
Video on the desktop: Off
These are good, right?
