Have you tried capturing to a file and looking at the output?

Like cat /dev/video0 > /tmp/somecap.mpg

Let it run for a while, ctrl-c and then

mplayer /tmp/somecap.mpg

To me it sounds like you have a bad cable connection, or a driver problem.

I didn't see where you mentioned how recent your ivtv driver is but you
might try upgrading it.  I suggest you get the above cat/mplayer to
look good and then try MythTV.
