For months now, when a channel appears which I click on, two thirds of the screen is filled with this message: Your TV or its cables are not HD. It lasts for about 10 seconds and then disappears.(It also says to press and hold down EXIT key on my remote). First of all, my slingbox connection comes from my notebook PC, via HD cable, to my HDTV. So this message makes no sense.
In any case, why can't I avoid having this message appear?
