I'm new to the Genesis and last night was trying to hook one up. I figured, easy, right, it's just an rf and power supply. Wrong. This is my situation:
I tried to hook up two difference Genesis 1 consoles. Same result with both. I put the RF from the console to the vcr input, attached the power supply. The sound came out fine, the picture came out, but the picture just about rolled vertically with both consoles. Could I be using the wrong rf or something? Maybe something about passing through a vcr via coax? The TV is fine as it works with everything else... but these Genesis consoles didn't want to work properly and the fact that they both did the same thing leads me to believe I did something wrong.
