In the next month or so, I'm thinking about purchasing a PS3 and using it as a Blu-Ray player. Obviously, I want to connect it to my surround sound system if I do. The only problem is: the way you connect anything into it is through digital out. But, the way you connect mostly everything these days (including the PS3) is digital optical. Is there any kind of adapter or alternate cable that can be purchased to connect the PS3 to the surround without having to settle for the component cables? )<--Which will deliver less than stellar sound.)
