I live midway between the 2 transmitters. We have noticed issues with 2 recordings of some same programs eg BBC1 on CH1 and BBC1 on CH800. I've tried to disable either transmitter group or individual channels - to no avail. My sony TV doesn't seem to let me edit auto/manual tuned channels. Similarly I can't seem to find a way to eliminate any from the broadcast GUIDE. Any suggestions welcomed. Is it a SONY tv issue, an EPG issue or a Youview issue?
