I'm talking about a digital cable converter, not a DTA or a DVR. Can you set a program in a digital cable box so it will change channels at a certain time when the TV is off? I'm aware that only one channel can be recorded on a VCR at any time -- the one the cable box is tuned to. I read something that said you can program your cable box to switch channels, thus enabling the VCR to tape whatever channel you're tuned to. Is this correct?
