Ok, I don't know which I need to do, I have the windows firewall, but that's it.
Here's what I'm trying to do, I'm trying to use a program called TVersity to watch AVIs on my 360. It said something about opening that port. I disabled the firewall and music worked, but Videos wouldn't show, I put the videos in there last time when I found out how to open the port or w/e and they worked...
