I have an old Response Transender+ that I bought before I realisied the joys of cable irda remotes. It's back out of the loft now that sky+ is in. Sure I can watch the channels in the other room but the remote control is very very intermittent. Any ideas on how I can improve the remotes response. I have played with the little IR blocks for hours now and no position is perfect. I go back in the other room and after a channel hop or two..........nothing! What am I doing wrong?
