First, do you see black borders just in the video, or in your MythTV menus, as
well? If the former, then have you configured MythTV to use separate video
modes for menus and for video? If you DON'T see borders in your menus AND if
you've NOT configured MythTV to use different video modes, then it sounds
like the borders are in the source material. If so, you should be able to see
the borders in the previews shown in the recording list, or when playing the
files in mplayer or other tools in a window. IIRC, this can be fixed by
adjusting the displacement and scaling settings in MythTV. Go into the
playback settings; these options are on the second page. I'm not 100%
positive those are the correct settings, though; I could be confusing them
with something else.
If you see black borders in menus OR if you've set the system to use different
video modes for playback, then it sounds to me like your video configuration
is off -- or alternatively, that your TV/monitor isn't properly synced to
your video card's output. (To be sure, if you're using a different mode for
playback than for menus, you should disable this option.) If I'm right, you
might be able to improve matters by using xvidtune to sync your display to
your screen and/or by adjusting the picture's position on your TV/monitor. If
you use xvidtune, you may need to create a custom Modeline from its results
to put in your /etc/X11/xorg.conf file.
