[mythtv-users] ABC-HD Slow Playback

I am trying to playback shows recorded on ABC-HD PROGRAM: 3: 7.1 KMGH-HD in
Denver. The video and audio playback are extremely slow, like they are being
played back at 1/2 speed. I have read around and it looks like ABC
broadcasts in 720p unlike most of the other stations. This happens on live
TV as well. I am running the RPM version of .20-fixes
(libmyth-0.20.1-157.fc6). Strangely enough the video preview plays just
fine. When I did a nuvexport, the export is perfect as well. I have tried
doing a mythfrontend -v playback and found the following:
