A VCR has a TV tuner inside it.
When you record something on a Video you are NOT using the tuner in the TV, but the tuner in the VCR.
And the tuner in the VCR will be analogue, and so is not picking up a signal any more.
So your VCR is NEVER going to be able to record programs from the TV tuner inside.
I believe there are ways of wiring up a VCR so it picks up the signal from the TV tuner (but I have never done it).
As has been said, you can continue to play VCRs.
You may now need to buy a digital recorder thingy, with a hard disk in it, which is far better than using video tapes anyway.
