I have setup my Drobo with FireFly and the server is running. Now I would like to get my AppleTV to “link” to FireFly media Server. How do I do this? Do I still need iTunes or does AppleTV do the job for me.
I can see the “Drobo” on iTunes on the PC but my aim is not to have the PC running with iTunes. Does this work or is iTunes a must?

See this thread.

In summary: not possible with the current version of Firefly. You can ‘jailbreak’ (strong word, actually the procedure is much simpler than that) your AppleTV and use XBMC with it.

I have an XBMC + AppleTV + DroboFS combo that works perfectly. In that case you don’t need anything on the Drobo side, just stream over Windows File Sharing.
