HD Satellite set up help please...

[MrElmo]

Hey guys. I'm Elmo and if its ok with you I'd like to consume some of your knowledge!

I will soon be a proud owner of a full HD Panasonic Plasma and want a HD satellite set up to complement it.

Firstly I have and can only get Broadband through my BT line and my provider is O2. No VM as the gas board have blocked off the access points on my street which sucks
Does this mean I'm screwed??

Now then Please if you dont mind what would be the best box to buy bearing in mind I'd like one with a Hard drive and the ability to record and watch at the same time. And obviously pick up as many HD channels as possible.

Secondly I'm assuming i'll need a motorised HD dish? what size? is it a case of bigger the better? What are the best models??

Sorry to be a pain, if I've posted in the wrong bit I apologise in advance and i'll sort it when I next log in.

All help appreciated

Elmo
