i have just wired up my sky+ to my house's RF system, it was installed for cable tv but works just the same for this. anyway, my normal TV channals come thru fine, i even have a Thomson digital box attached and that works fine. the sky on the other hand is another matter, the picture comes out with horozontal lines as you can see below, at first i thought it might be off the movie channels.. but it doesnt seem to matter. i havent tried changing the modulation channel yet. its currently on 68, which i think is pretty high, there are faint channels on 64 and 61 and 58, would it be a good idea to look for a clearer channel group perhaps? thanks Memphis.
