 [Although this is specific to a recording profile, I'm filing this under
 "Video Playback" because that is the part that has changed... recordings
 made with 0.21 behave the same as recordings from 0.23-fixes]
 [Also, the mixed versioning is because I don't currently have the
 0.24-fixes test system up and running..]

 MythTV versions from 0.22 onward display graphical artifacts (including
 the top fourth of the screen being green) when playing recordings made
 with the "Low Quality" recording profile (with a PVR-150). The same
 recordings play fine in 0.21 as well as other players (including mplayer,
 VLC, and the Windows MythTV Player client). An example is currently here:

 - Different playback profiles/filters make no difference.
 - I've tried four different computers (via Mythbuntu LiveCD) to rule out
 hardware incompatibility.
 - "--verbose playback" didn't seem to indicate anything unusual. I can try
 it again and attach the log if that's of any interest.
 - Behavior is identical whether streaming from the remote backend or
 playing the files locally via MythVideo.
 - The commercial flagging process crashes for these recordings (again,
 0.21 was fine). That's a more difficult thing to experiment with and
 investigate, so I only mention it because it may share the same root
 issue. I'll attach logging for this just in case.
