I've so far tried A and B with no luck. I'm going to now try a remote recording to see if that tricks it into starting up. Failing that It will have to be D and lose all of my current recordings. Bit annoying as I have some films on there I wanted to watch, plus last nights Battlestar Galactica episode Although that is repeated tonight so I can still catch it if I can get the box working again so I can set it to be recorded!
