So I decided I'm tired of this never working and have spent some time trying to make it work. My big success so far is that WMP 11 (and my OS, XP with Service Pack 2) see the Xbox! Media sharing has been enabled. Now I'm stuck though. The XBox can't see any PCs, and the connectivity test fails at "Selected PC". I've opened the list of ports it says to open in both my router and the Windows Firewall thing...looking around online, I've had trouble finding any answer I could use. Anyone else have any experiences getting this to work?
