Just a question I have the 500GB dvr and once in a while when I turn the box on after it is off say overnight it comes on, the tv works and I get picture but the display on the box is flashing the channel #. If i hit any button on the remote the flashing stops and it stays steady. Just wondering what that means? I have been having other issues with the box so if this is another one then I'm gonna have to address them all.
