My main multimedia box is a PS3. I also have 4 DirecTV H24/HR24 receivers on the same network. The DirectTV recievers see the media server immediately, but the PS3 usually has a delay of several minutes. The receivers are all on a wired connection, the PS3 is cabled to a Wireless bridge from the router (Wireless N).

Obviously not a firewall issue since the receivers pick it up immediately. Also, the PS3 picks up the two DirecTV HR24s immediately as media servers, so the network communication is fine.

Any solutions, here?
