Have had the DVR for a couple of years and no problems. Have some programmes on series record. Went to watch some over the weekend and when I click play on the episode the screen goes black...and then back to the last tv channel I was watching. Tried some older stuff that I'd watched but kept (in case it was a new recording issue) but same problem. Memory less than 50% full.
Mine doesn't work at all. All recordings have just disappeared. I'm moving back to Sky; the hardware UPC use is rubbish. The digital box (Sky+ type box) is so slow that I often think the remote control isn't working. The menu in the standard boxes can take up to a minute to load. Utter rubbish!
