I. A splitter isn't the best option to run two inputs to one TV. You will get a lot of interference on the channel (3 or 4) you choose your satellite RF Out to be.
II. What outputs are on the back of 400 series receiver?
- If there is a composite (yellow, red white), you should hook that up from receiver to VCR, and have your CATV directly to VCR.
- If there is NOT a composite out on receiver, then a better option would be to buy a signal combiner. you hook up RF out from receiver to input on the combiner (can be either channel 3 OR 4), and the cable to the other input. then the output will hook to your VCR. downside to this is you won't get CATV channel 3 or 4 depending on which combiner you get.
