iPlayer on PS3 is pretty good, the quality is almost broadcast...and I live in the middle of nowhere

I'm looking forward to the other terrestrial channels being made available soon, fingers crossed. Of course HD iPlayer would be a bonus, but I don't think I'll be using that until they can upgrade my exchange to 24mps.
I worry with this Freesat change though that you will need a new Freesat box. I haven't got one yet, and I'd be loathe to buy one if I knew that they could become obsolete as quickly as this generation of boxes might have done.
