If you are using an HDTV converter box along with an antenna to pick up digital broadcasts from the air, then you have an antenna connected to the converter box and then a cable going from that box to your TV. To hook up a VCR, just connect the cable from the converter box to the back of the VCR, then connect the VCR to your TV. That way, the converter box is running through the VCR so that it can capture the signal and record. Even if you are not recording, the signal will pass through the VCR.
The easiest way to connect everything is with coaxial cable, which is the thick cable that has a copper wire in the middle and screws into the back of the unit. Coaxial won’t give you the best image quality, but it all depends on what kind of TV, VCR, and HDTV converter box you are using. If possible, I’d recommend using component cables or s-video. Anything is better than standard coaxial.
