I'm in the UK and have a Sky mini dish with a quad LNB, with cables running to each of the 4 rooms. I don't want to subscribe to a card sharing service from a third party - I just want to share a single Sky card between 4 boxes at home.

So here are my questions;

1.) Which HD box should I buy? I guess it will need a LAN port?

2.) How do I connect the Sky card to my PC?

3.) What server software do I need to share the card?

4.) What client software do I need to install on the boxes?

Thanks in advance for your help!
