i have a brand new samsung tv with a digital audio output, my bose surround sound only has the rca connection....is there a converter for this or is my 900 dollar surround sound useless ?
Well, you can get a converter (http

You should have an AV receiver to run all this through, there are some good budget models out there from Denon, Yamaha and Sony. Denon seems to have the best upconverters if you watch a lot of non-HD content and you have an HDTV.
