I used the attached script to fix mine.  I run this out of cron once/day
and I very rarely see the bars anymore (and if I do I just run the script
by hand :-).

The one nice thing about this script is that it resets your input to what
it was before the script ran -- this is very important if you record from
both the s-video and tuner.  :-)  It also makes it safe to run while
watching or recording -- it switches away and back so fast that you'll just
see a quick "blip" and then the bars are gone.  :-)
