My father-in-law's box locked up during the rescan (found all the muxes, found all of the appropriate stations, then hung saying "wait", or words to that effect).
He power cycled, and after a couple of cycles where the box was unresponsive there are (apparently) no lights on the front now. Sounds like coincidence to me, but I'll get my hands on the box at the weekend and have a quick play - probably a PSU failure. Anyone else seen this?
