I have 2 Tivo boxes, one in the sitting room and one in my study, both of which I have had for about 4 1/2 years. The study one is fine, it is the much more used box in the sitting room that has started playing up. While it has always been quite slow and clunky (compared with Sky), it has recently got noticeably worse. So it seems to take (at least) 5-10 seconds to respond to every click of the remote, for example. And deleting anything takes even longer.
Worse than that, though, is the constant flickering of the picture on playback of some recorded programmes. It happened throughout Match of The Day last Sunday (23rd), which made it almost unwatchable. But for some unknown reason, testing the box by playing back The Pursuit of Love just now was fine.
Do Tivo boxes, or their hard drives, wear out and need replacing? Or is it something else altogether?
I would be most grateful for experts' thoughts on this mystifying problem.
