Sky+ Woes

I have decided to 'sell my soul' in subscribing to Sky Digital.
At the moment I have a Freeview setup with a 40gig hdd PVR.
One of the conditions of me moving to Sky is to opt for Sky+, I simply CANNOT revert to a PVR-less experience. Those key features of rewinding/pausing/recording live broadcasts on-the-fly have revolutionised our Television viewing experience, and we simply cannot do without them.
So you can imagine my dismay when I discover that our flat is NOT equip to receive Sky+.
Reason is because we have to receive Sky Digital via a communal satellite, as we are not allowed individual satellite installations due to the terms and conditions of the area.
Sky+ requires two feeds/ports to connect to the box in order to use its dual-recording features. Our flat only has a single feed/port meaning we can get Sky, only no Sky+.
Let me add that my property is meant to be a £175,000+ dwelling with all the mod-cons, yet due to short-sighted construction, we are stuck with 20th century technology and not the 21st century benefits of a dual-recording digital PVR. Let me also add that when the communal dish was erected in 2004, Sky+ was an already existing technology.
There is unfortunately no way around this, as Tower/Bellway homes (whom I promptly contacted) so abruptly told me. Apparently we are to be grateful to receive Sky Digital at all and "TV is a privilege, not a necessity" - THEIR words, not mine.
I told the housing people that I would form a petition that the local residents will sign to 'encourage' them to at least replace the communal satellite setup with an installation that is technologically 'in-date'.

I will distribute the petitions tonight, and await the feedback before I take this case further.
