I have just purchased a JVC DRMV1S DVR Recorder / VCR combination unit and have a few queries. Here is one: Lack Of Terrestrial Aerial Currently I don't have a terrestrial aerial connected - just cable. Will this cause any problems? I realise this means I can't take full advantage of the two tuners but will the unit still operate OK? Should I turn the clock "Just On" feature off or will this operate off the cable signal?
