I have a mate who has just had sky HD box upgrade and i must say i was impressed changed channels quickly and the picture quality is good,he does not have anytime though as he has no phoneline and if he did 1MB may not be enough to do much.
Have had TiVo installed today as an upgrade myself seems a good box easy to use and set up express series links on,on demand seems to work better then my V+ and it has a good UI,although TiVo woud work better for me due to the MB problem on the phoneline (for on demand ) i could not in all honesty say which is the better box overall.Though am missing reminders already hint hint..
As skys is loosely based on TiVo technology also.
