I'm glad I found this thread, becuase I have a very similar question that will probably pertain to the original poster.
I too have a Denon 1930CI, and I am looking to get into SACD's. I have yet to buy my first one. I noticed many are hybrid SACD's, which of course have the SACD layer AND the CD layer on the same side. I started wondering, if I put such a disc into my DVD player, how does it know which layer to read? I finally found a brief article somewhere that stated DVD players won't play SACD on hybrids because DVD players look for the CD layer first. Can anyone confirm or deny this nasty rumor? Most of what I want only seems to be on hybrids, and if my player won't read the SACD layer... I guess I'm hosed.
