i am trying different upnp servers on the same host (= same interface and same IP address). should that work cleanly or is it supposed to create problems? at lest all upnp server have to listen on udp port 1900 ? i am expierncing strange problems as not all upnp servers are always listed on the control points... some times there is only one, sometimes there are three etc... (testing minim, twonky and logitechmediacenter (aka squeezecenter) together).

This should work OK, but I have heard about problems when using an older version of Twonky (5.1.x) in combination with MinimServer. This was fixed by moving up to the latest level of Twonky. I'm not aware of anyone who has tried using SqueezeCenter together with MinimServer.

To narrow down the problem, can you try running MinimServer with a recent version of Twonky (but not SqueezeCenter) and see if this works OK. If this combination is working OK, can you try adding SqueezeCenter and see if this causes a problem.

The UPnP discovery protocol uses UDP multicast, which is an unreliable protocol and can be adversely affected by a wide variety of network-related issues, especially when using a wireless network. I've had to debug and work around a number of these issues on my own network. A good first step in the debugging process is to try this with a fully wired network and see if that improves things.
