Sorry, I'll explain it better.
I've got my VCR connected to the antenna socket of my tuner, and my antenna plugged into my VCR, as a result when I tune, the VCR should be watchable on one of the channels (just like a TV station).
The setup is fine, because on the app the came with the tuner it works fine (the VCR is watchable when I switch to CH 37)
Thanks
