I have tried various tests. When I "cat /dev/video0 > test.mpg" after
"ivtv-tuner --channel=24" and try to open the resulting file in mplayer I
get a screen full of coloured squares and the following output:

Playing test.mpg.
RAWDV file format detected.

tvtime /dev/video0 gives me the same flickering coloured dots but at a
higher resolution.

mplayer tv://dev/video0 gives me a solid green window and
mplayer pvr://dev/video0 gives me:
