I am currently at the planning stage of a home cinema installation. I am trying to decide where best to sit the speakers and wondered whether a 7.1 system would offer any real advantages over a 6.1. As far as I am aware, not all DVDs fully support even 6.1. Do any support 7.1? Is this something that may be more important in the future? Sorry, if this is in the wrong place. Cheers, Beastie.
