ray and get surround sound? Hi, I own a Sony Bravia DAV-HDX275 5.1 Channel that I bought in 2008, but it plays regular dvds. If I buy a sony blue ray player, can I somehome hook up the sony blue ray player to my theater system and still get sound out of all the 5 speakers and subwoofer? I hooked up my cheap regular dvd player, and my theater system only plays through 2 speakers, but it plays all 5 when used on its own.
