MPEG TS HD Videos won't play

I have recorded TV Via my HDHomeRun, and some of the shows won't play. some will play sound, but no video, and some others play just fine.

As an example, the show Castle won't play at all. This has all been recorded as free over the air TV. Any ideas?

I'm a new user, and would like to start using the new PVR functionality once it matures just a bit. I am running Beta 1 - repack.
