I usually see it on The West Wing... worse on the "Bravo" rebroadcasts than
on the mainstream NBC stuff.

Also, just to point out... if the contrast is off on a channel badly, it 
really confuses things :-) I doubt there is anything you can do about it...

My cable company broadcasts Bravo "way off" and a "black" screen shows light
grey... I can adjust the brightness and contrast of that channel and get it
back to about right, then the commercial detection works again. My problem
here is that the settings don't always "pick up" after mythbackend restarts...
If I go to that channel and "fiddle" with it, it works.

I'll send that in a seperate head's up for somebody to look at if they care.

Thanks,
Bruce
