That's normal. NTSC/PAL were designed such that display devices must
overscan the video so that users don't see the borders (having black
borders/rainbow borders/jagged edges/other visually-displeasing
characteristics). Black borders are extremely common on
composite/S-Video inputs. Tuner inputs often have jagged edges and
"purple/green rainbow" borders.
So, overscan your video output (using either MythTV's overscan setting,
your video driver's overscan setting) or crop the edges during playback
(with MythTV's crop playback filter).
