If it's lots of horizontal lines, like a the picture's been combed,
then it's probably a deinterlacing issue.

If it's just a few horizontal lines, with the parts of the picture
above and below the line slightly out of sync, then it could be
'tearing'.

... which help you google.

I'd start by looking at the playback profile in mythfrontend setup.
