Thanks, got my HD Golf back. Should have known to rescan but listened instead to my "provider" who reckoned we had lost them. Haven't done a full rescan yet cos damn thing was locking up or going really slow, seemed to be relatively stuck at 42% with only 249 channels found. The clock had stopped as well.Rescan your channels
Rebooted and got the golf back on so will try a full rescan again later.
