OK. Runninng MAC OSX 10.8.2
Connecting with a PS3.
PS3 sees the media server, BUT, always gets the 7531 error. I have searched and searched and tried all the suggestions on here, but they seem to relate to much earlier versions.
Extra info. Netgear Router, uPNP is enabled and I have also forced UDP 5001 to be allowed..
On the PS3 have disbaled and re-enabled the media server client.
Please any more suggestions.
I can post log files if required.
