I have a Denon AVR1912 which is connected to my home network via a BT home hub. My problem is that the Denon seems unable to see the contents of the NAS drive (Netgear). It's quite happy to pull files off a laptop and my SONOS system can see the files perfectly well Do I need to add any addtional software to the NAS drive to make my audio files visible to the Denon?Thanks for your help.
