Tonight, totally random and out of character my little Hummy started Freezing and going to a black screen I rebooted it, and it seemed alright for about 20 mins, and then the same thing happened. I've rebooted it at least three times, but it still freezes randomly. Luckily I've just bought a second unit and am awaiting its arrival. It's not related to any channel ( they all do it) its got CFW 3.00 installed. Is there any point in upgrading the firmware? Another fault it has sometimes is failing to record by the schedule. Any help would be gratefully received.
