I just purchased Ryan Adams Gold DVD-Audio. For the multichannel mix, I found that I have no center channel and no subwoofer. Is this correct? Was this only a 4 channel mix for DVD-A? Or did I buy a mis-mastered disc? What about the SACD's multichannel mix? Is it also 4 channel? The ironic thing is that I was at the Largo last weekend watching Glen Phillips, and Ethan Johns (who produced and recorded this album--both stereo and multichannel) was sitting in the table next to mine. If I had owned this back then, I could have just asked him... Thanks for the help!
