I don't have a pioneer receiver on the network, but there is plenty of other "stuff" on there. 3 computers (one of them is the Windows Home Server), 5 Sonos players, a couple iPhones, an iPad....
I did a little playing around before leaving for work this morning and disabled DLNA on the player and it seemed to fix the freezing issue, but now is there any way to access files from the server? I rip all my blu ray's off onto the server for ease of use and if I can't get to them with this player I might have to continue my search for one that can unfortunately.
