Well, I've got the mythbox script for XBMC working happily for recorded shows, but with some slight audio stuttering for live TV, which disappears if I rewind a few seconds.
Edit: Getting a lot closer and happier using a pre-built Windows frontend.

There's WinMyth and you can also try MythTvPlayer but their both still quite experimental so YMMV

I just use XBMC with MythTV's UPnP support. Works well enough for playback, but don't have as much control as a proper Myth Frontend; and doesn't do commercial skipping.
