I can't seem to view the channels on my VCR, nor can I record off of them. Heres how I have it set up, let me know if this is right. Cable comes into the house and goes to the in on the cable box, then goes out from the cable box into the in of the VCR then goes out from the VCR to the back of the TV. Thats how it should be hooked up right? Now what else do I have to do to get it to work?
