One really stupid question.. just got a Pio 633H DVD recorder and trying to hook it up to my ancient TV. The TV has only VHF/UHF antenna input (yes I know). Anyways, I don't see any picture from the DVR when I switch to CH2 or any other channel. Do I have to use video outputs from DVR and just using the VHF/UHF output won't fly? Google could not find any answers, so here you go.
