I'm trying to connect my Panasonic DVD-recorder (DMR-HS2) via an RF antenna cable to my old TV, which doesn't have SCART. However, this doesn't seem to work. (When I connect it to my newer but smaller TV it works fine both via SCART and S-Video.) Is it not possible to connect a DVD-recorder via the RF antenna cable? My relatively new VCR works fine connecting it only via the RF antenna cable.
