DLNA Protocol Error (7531) Has Occurred

[Larry1]

Hi, I am currently using TVersity version 1.97 on a Windows XP and Windows 7 OS.

I use TVersity to play media through my Xbox 360 and Playstation 3. I don't have problems with the Xbox 360 (apart from it not being able to play certain x264 encoded videos), though I constantly receive a "DLNA Protocol Error (7531) Has Occurred" on my Playstation 3 and it is either unable to detect the media servers or will stop responding during media playback.

I have searched many of the forums and have been unable to come up with a solutiion to the problem. I am using a Netgear N600(WNDR 3700) wireless router and a Netgear modem (DM111P).

Please help me to solve this problem, as I'm unsure of how to fix it myself. Any assistance you can give will be much appreciated.

I believe the problem is due to the firewall setting on the router. Now i'm no expert, but i have made the below changes on my router which seems to have resolved the problem (for now at laest)

On the Advanced setting, UPnP settings (Which is enabled)
I have decreased Advertisement Period (in minutes): from 30 to 10
and
Increased Advertisement Time To Live (in hops): from 4 to 10

For me this seems to work... Not sure what all this really does but it seem to make sence... I think i have all by to do with the amount of time the router checks and keeps the ports open to allow packets to pass through to the playstation....

Try it and see if it helps.
