Denon DVD-3910 digi out?

I just checked my 3910 and I don't see a firewire port period. It does have a digital output section, and in it there is an optical jack and a coaxial jack, that's it. Further, no player outputted the hi-rez formats digitally when 3910 was released, so it seems unlikely this would be an exception.

Not sure about the 3910. Denon 5910ci lets you pass multichannel DSD (SACD) and DVD-Audio using 1394 connection, as long as the receiving device supports DTCP copyright protection -- can't plug into a PC.

Depends on the software version you have. Check with the Denon website for upgrades.
