Hi there, I moved to a new house a while ago, but have recently discovered that the old owner has a RF cable going out of the lounge up to the loft to a distribution amp and then back down to the bedrooms and the kitchen. So over the weekend I thought I'd make the most of it, I taken the output from my Panasonic DMR-E55 DVD recorder and sent it back up to the loft and it works perfectly. But as soon as I try to put the external RF into the mix things start to go wrong because it seems that both Channel 4 and the DVD Recorder RF out are on channel 21. I've also tried going through the Sky+ box rather than the DVD recorder, but this has exactly the same problem. Anyone got any ideas as to how I can change the RF output channel??
