Alright, I will try it. Thanks for all the help. It seems pretty irresponsible of Microsoft to just turn on UPNP for everybody.
Also, does the UNPNP program to disable the UPNP on Windows not for Windows XP Media Center? It worked for me on XP Home and Professional but not on Media Center. Is there a reason for that?
I think, but am not certain (only 99%), that Windows Media Center requires network UPnP to work correctly. -- "People demand freedom of speech as a compensation for the freedom of thought which they seldom use."
