I had the same issue with ABC HD in Raleigh from OTA. I'm convinced  
MythTV doesn't handle 720p content correctly which is what ABC  
broadcasts. I say this because if I tuned OTA ABC with mplayer  
outside of MythTV the picture and sound were perfect. :)

Despite my above statement, I also give MythTV props for having  
billions of knobs to tweak. Enabling the "Extra audio buffering" (See  
Setup -> TV Settings -> Playback -> General Playback) solved my  
problem with ABC and didn't affect the other OTA channels one bit.  
You might give that a shot.
