MSEARCH sometime failing

[AlexDmr]

Hello, first thanks for this module wich is very helpful to me! :) However I encounter some problems during the MSEARCH. Sometime it goes right, I can detect every UPnP device that is present on the network, but many times I get stuck : the only device that is detected is my local computer, its adress is 127.0.0.1, if I launch XBMC then it is also detected but the adress is 127.0.0.1:... Every other UPnP device that is not on my computer just never appears, whatever how long I wait for it. Those times I have to restart the msearch (and actually my whole programm) some times before everything get detected. My OS is windows 7. I suspect that the UDP socket is sometimes only listening to my computer but I don't know how to properly configure it. I implemented a UPnP stack on TCL language few years ago and I encountered the very same problem as long as I was using my own multicast UDP sockets, so I had to include into my code the intel UPnP library (well, the part of it that was related to SSDP actually) to make it works properly, that's why I suspect here a socket configuration problem.
