Re:Need a new Sky Digibox
Have you tried phoning Sky? They might fix it for 65 quid.
Failing that, when my Sky Plus box packed in a couple of years agio, I strongly suspected it was the hard drive so just got a bigger one of the net and put it in myself. I got a 'kit' rather than just the hard drive so I was sure it was going to work, cost a couple of quid more doing it that way.
