We just replaced our comcast cable with dish network and are having some tivo troubles now. Our receiver is DN's 322 and we have a series 2 tivo with the dvd player. The receiver works fine wired through the tivo, but as soon as I turn the tivo the fun begins. After finally getting picture to show on the screen with the tivo powered on(had to use rca a/v cables as the coax wouldnt work) we cant change channels through the tivo. You can go to change a channel through the tivo, but once you do you get a blank screen. If you try to record something all the gets recorded is what is currently showing on the screen(any channels you change, menus you go to, etc). Just really confused and want to be able to set the tivo up so we can start to record shows again. I looked and searched around here but didnt really see anything like what I'm experiencing. Any help would be great. Thanks.
