I have a few upnp devices on my home network - A Netgear NAS Duo, a Naimuniti, and an Xtreamer Media player.
I've mapped a drive to the NAS on my Windows 7 laptop and this works fine- The Naimuniti and the Xtreamer also can see the NAS and stream music/video etc. and in fact the Xtreamer sees my laptop but Windows 7 does not see the Xtreamer.
I've also installed Tiversity on Windows 7 but this does not see any of the upnp devices.
I've turned off the Windows 7 firewall but still no joy.
Any pointers would be appreciated.
