EX4100 network and itunes problems

I just purchased a EX4100 and populated it with 4x 3tb drives, the intension is to back up via acronis, and use the iTunes server, I run two pcs.

So first headache, machine 1 sees the ex4100 on the network, and I can map it.
the second machine does not see the ex4100 on the network, I can access the setup pages via the ip address.

The second problem is iTunes related. I have moved all my movies to the nas, and enabled media and iTunes server, but iTunes only see the music (on both pcs), it is not allowing TV shows or films. (all original) they work via mapping, but again only on the one pc…

any help would be gratefully accepted

Hello,

What operating systems are you running on your computers?

What’s the file format of the TV shows and movies?
