Ok, so I'm all moved into my new house and finally have my equipment squared away and have started listening to my DVD-A and SACD discs. I guess everything is going to DualDisc now? I am somewhat confused because as I strolled through Costco last night, I saw the new Springsteen album in DualDisc. The problem is that the label states something like CD on one side and DVD Surround Sound on the other. What the hell is that supposed to mean? Is the DVD side DVD-A/MLP? SACD? What? Also, I have a hard time finding an internet retailer that actually has detailed specs on what's on the DVD side. Am I just missing something?
