Programming Quasar VHQ940 for DTV converter box

I assume you're trying to record from the DTV box. You will have to set the DTV box to play through channel 3 then tell the VCR to record channel 3. So basically the VCR always THINKS it's recording channel 3, but in reality it's recording whatever channel the DTV box is on. You will be unable to used timed recording unless you leave the box on whatever channel it is you're wanting to tape.
