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.
Denon DVD-3910 digi out?
Does anyone know for sure if the firewire (1394) port on the Denon DVD-3910 will output SACD and DVD-A . Almost all multi-format players will not digitally output SACD or DVD-A . Does anyone know of any that do ? Maybe in the pro-sound/studio area?
