I found on net this great application. Maybe someone will be interrested.
Also it is good for finding problems why PMS is not working
If you don't see on the left PMS(upnp server), it is PMS or OS related problem.
If you don't see on the right PS3(media renderer), it is in most cases network/firewall related problem.
Also very good project here(less beta as 4u2Stream and with more features, compatibility etc...):
Cidero is very good for testing purposes how it will looks on PS3, what exactly some option(hide extension,media library,etc.) do:-) Great when you are away from PS3!!!
Also good Debug Window where you can see UPNP communication
You can see Search, Subscription, Alive Notifications, ByeBye Notifications, Action and Event messages without WireShark....
