I have the basic £16/month package and a Sky+ box (installed 8 months ago). I want a Sky HD box so that it provides a HDMI connection to my LCD TV (Sony KDL-40D3500), and to receive FTA HD channels. I'm not interested in Freesat until a PVR version is released. Can I simply buy a Sky HD box off ebay and plug it in? Do I need to change the LNB? What, if any, FTA HD channels (e.g. BBC HD) can I receive if I don't have the £10 HD subscription.? Sorry for all the questions, but I'd thought I'd ask them all in one hit! Thanks in advance.
