Are you using MythTV? If so, have you by any chance set the option to use a
custom video resolution based on the recording resolution? If this is the
case, the black bar you're seeing could be caused by the playback video
resolution for 720x480 producing a slightly smaller image than the playback
resolution(s) you use for other recording resolutions.
