I've just bought and set up a Marantz NA7004 network audio player. After a little bit of faffing around, I managed to add it to my home network, so that it could "see" and play music files that I already had on my pc. I then ripped some new music to the pc using iTunes, but the Marantz doesn't see the new stuff, only what was already there when I set it up. If I try to play the new stuff from the pc end, using Airplay, it's fine, but if I try to navigate to it from the Marantz's end, it just doesn't appear in the menus. Anyone got any ideas, cos this is baffling me?
