Had anyone heard of this happening? I've just bought a new TV so have been using Freeview HD for the first time - on the TVs tuner. Problem is SD signal on BBC channels now seems screwed up. Both on my SD Humax PVR and my TV's tuner. I'm a bit stumped really. Could the HD signal be ruining the SD signal? Maybe its just the crap weather we've had recently..? Any ideas? The girlfriend is getting all shirty because her recordings on the Humax are screwing up!
