Oh, for crying out loud. Did a bunch of software updates to try and fix slightly glitchy terrestrial HD freeview on my Media Center, and created another problem: since I updated to EPG collector 4.1, I'm getting dots replacing programme data in my EPG. ARRGGHH.
I see there's been discussion about this before: did anyone figure out the root cause and a fix? There seemed to be some debate about which registry setting to mess with (why am I having to mess with them at all? This didn't happen to my guide a week ago!)
