Well hopefully the quality will be good enough. As I say, when I ran the composite (not component, composite, as in the single yellow connection) connection from Sky to my aging AV receiver and into my TV (which can accept RGB signals) I thought it was fine. When I ran the same Sky feed using a direct RGB scart to RGB scart on the back of the TV, I didn't notice much at all. Maybe I'm a freak, maybe I need my eyes tested
I suppose I also need to bear in mind for a few months my wife and I used bog standard analogue, on a bad signal, so we had grainy, interfered tv signals, and only 5 channels.
We used to have Sky, then got rid of it because all the stuff we wanted to watch was on at times we couldn't watch it. Wasn't prepared to spend the money on Sky+, so cancelled. However, if the quality is good enough, I'm willing to pay the standard Sky subs to use it with my MCE machine.
So there you go, it's not good enough for some, but good enough for others. I guess until I see it, I won't be able to comment.
