If you leave the AFDM on, Denon themselves tell you that mistakes will be made since every dvd manufactirer does not properly flag their disks. In other words, you can;t trust the AFDM to do the right thing which is not the 5800's fault. Therefore, by leaving it off and the matrix mode on, all your DD 5.1 will be presented in a simulated THX-EX mode which is great and it will also detect properly encoded THX-EX disks. As for DTS-ES, the computer picks up the difference with or without AFDM on so you might as well leave it off. Denon recommends leaving it off anyway. You might want to ask why bother including the feature at all since it seems to be a negative in any case. I can't answer that other than specific and rare uses where a customer may want the thing on to access other options.

Do you have the Auto Flag Detect Mode (AFDM) set to ON or OFF, and why?
