After powering up PVR I get the message du1 and the channel. There is nothing on the screen. I then access the input button and find that it is not on cable setting. I then go down to cable and the sound comes on but I get the "No signal" I then go down further to the other "Cable" setting and up comes the picture but not in the size I want. I then go to the TV's remote and have to adjust the picture size to the one I want. Changing channels is very slow. I then set the TV's remote back to cable/ant from TV. I have to do this every time the PVR is turned off. I have tried everything suggested by your site with no success. Getting tired of this. Any help I can get is appreciated.
