Sky Anytime? Useless in my opinion.
They pick 2 programmes a day (more or less
IIRC) and then automatically download them to your hard drive to watch later, although I never once saw something recorded on it that I might want to watch. I'm more than capable of picking my own programmes to watch at a later date... don't need somebody to do it for me.
That's the main problems really - it's just a random selection of a few very odd shows, and the odd big coup like a football match or a film, which have all been shown on Sky at a certain point, so you can achieve exactly the same thing yourself. It's only purpose in my eyes was if there was sod all on, and it happened to record something I would consider watching, although the chances of that, it seemed, were around 1 in 50.
I disabled it because it meant the box would start spinning up the hard drive whilst I was trying to sleep, and it never gave me any benefit.
