There are other benefits to using QTV, which you would not get with the regular spectator mode. For one thing, QTV viewers have no direct contact to the game server, meaning they cannot messagemode1 to the server and interrupt the game. The QTV proxy also allows you to create nice demos, which start recording right at the map change and also show the name of the player you are currently spectating. In addition, you can have real time voice communication among QTV viewers, as well as increasing your rate by as much as 2x due to the built in data compression. I'm sure when you hear the word proxy you automatically think of cheating, but that should not be the case.
Proxies can be both good and bad.
All a proxy does is sit between you and the site you want to connect to. Programs such as Wingate are proxies, which allow you to connect multiple computers to one Internet connection. Bots are also based on proxies though, since they sit between the player and the server, modifing the game data. For our purposes, we are using the Qizmo proxy to allow many people to spectate a game, while only one person is actually connected to the server. The basics will just outline how to connect to a QTV server and start watching a game.
