Ok I have a sony wega TV and want to get sound to my 7.1 speakers rather than using the tv speakers. I have the speakers hooked to my consoles, dvd player and would like the sound to play from my from my tv to the speakers when watching programs and shows. I have these speakers http://www.hardwarefusion.net/content/000302.php I have this decoder http://www.bzboyz.com/store/product2801.html I live in the UK. What lead do I need to hook it to the tv to get sound from it. I'm guessing it would be a lead that goes to the analog input of the decoder?
