Hello, Since I have my revue, some of my channels always have a warning msg when turn on the setup box something like " Copy Protection YPbPr output is blocked Press "exit" to cancel". But this morning when I first turn on the tv my screen was froze so I decided to restart the revue and after that those channels (the one who generally have the Copy message) are all black. I see the menu bar, the channel name but no image and song. If i go to the "same channel" (the non HD version) it works. By the way I'm in canada so my cable provider is probably not trying to block gtv, but could be something for copy protection.... Someone else had the same issue ? Thanks, I use a Logitech Revue + Atlantic Setupbox + Sharp Acquos.
