Doh! I saw the option for de-interlacing but the help text said it
would improve pictures on progressive displays such as monitors so I
didn't check it...
'Bob' seems to work well - scrolling text is readable now, mank thanks.
Mike.

These sound like interlacing artefacts, rather than poor signal.
Depending on the quality of the TV Out signal, you may be able to play
interlaced material without problems, but sometimes you will have to
deinterlace the video first before displaying on the screen (try the bob
deinterlace for instance, in the frontend TV Settings setup). This does
add extra processing requirements on playback, but shouldn't be a
problem.
