I just got dish installed for the first time, and I am having troubles connecting a VCR, DVD player, gaming system, and satellite all at the same time to my TV 2. My TV 2 only has coax input, my VCR uses coax or RCA outputs, and my DVD player and gaming system use only RCA. Before I had satellite installed, I had my DVD player and gaming system going into my VCR's two RCA inputs, and coax from my VCR to my TV. The Dish was installed when I wasn't home, and the installer disconnected everything, and just ran coax from the wall to the TV. I have tried the way that the instructions suggest, which is to run coax through the VCR to the TV, tune the VCR to channel 25 (which is what I have it set to), and tune the TV to channel 4. This does not work, and does not give me any picture. The only way I can get picture is to turn the VCR off and tune the TV back to channel 25. As I said, I am completely new to Dish, and I have no idea about diplexers or anything else, so hopefully there will be a simple answer to this problem. Thanks!
