Sorry it's a convoluted one: Sky Digibox (RF Channel 44) looped via rf to a Sky Plus box (RF Channel 46) then looped to a VCR (RF Channel 50) then via rf to an IR injector then to an IR compatible amplifier, then from amplifier to six TVs (all fitted with Handylink eyes), Cabling = CT100 or equivalent Ampifier = Labgear 8-way distribution amp with IR return (MSR380) IR injector = Labgear IR Remote Extender kit (MRX120) There in NO analogue TV aerial input. I have Sky Digital on Channel One I have Sky Plus on Channel Two I have VCR on Channel Three I have IR control of all three devices at all six TVs. So what's my problem? The picture is hazy and if you look closely there are fainted horizontal lines. I only have three RF signals travelling along the cable 44, 46 & 50 should my picture not be near perfect?
