Some days when I turn of the DVR and TV, I see a big error message saying that there is no signal on the current channel. All I have to do is change the channel and then go back to the original channel to see that it is present and transmitting. This occurs intermittently and it is not related to what channel is tuned - it occurs for the main network HD channels. All I can figure is that the Contour box is "giving up" at some time overnight on the channel. The box has been turned off the night before - so it is not sitting on unattended.
I wouldn't care except that I suspect that this is causing problems with my Onkyo receiver which is shutting down the HDMI pass-through support when the Contour box "loses" the signal.
Any explanation of why this is occurring? I have not experienced any TV outages when watching TV. This only seems to happen overnight when the TV is not being used.
