I found the Borderlands Configuration Editor, which is a great tool that easily allows PC players to do everything from disabling the opening movies to adjusting the field of view (FOV).
One of the "TO DO" additions to the tool is a "Check my ports" feature, which is dearly needed for the port forwarding mess that is multiplayer on the PC version of Borderlands. So, if you have a moment drop into the forum and place a vote to get this feature added ASAP!
