The problem you are facing is that you only have one tuner.
You use the cable box to tune your station, right?
Your TV and VCR tuner are now useless, right?
So, this forces you to make a choice as to which gets the signal first and which gets it second. In either case, whichever station one gets is the same one the other one gets.
As it seems to stand now, you have to turn the VCR on in order to feed the scable box signal through it to the TV.
You might have an alternative
If your TV has a video and audio output then you cah have that feeding your VCR's "aux" inputs and you would have to switch the VCR to use them. RTFM for this. Again, the TV will have to be on for the VCR to record.
You could always pick up a switchbox and select which is to receive the signal, but this would most likely require your TV to have two aux inputs, one for the cable box and one for the VCR's output.
