I've had my house wired to accommodate Sky+ & distribute the signal around the house. Now for the tricky bit. Before I call up Sky & order my system I want to make sure that I buy the right product. 1.) What version should I get...is 80GB really necessary? 2.) Am I correct in thinking that I don't need multi-room package? 3.) Are there any subtleties that I should be aware of in connect Sky+ to DVD etc. (SCARTS...) and also as I don't have a DVD player yet, is there a model I should look at because of its features & compatibility with Sky+ Any other advice greatly appreciated.
