Q: My QuickTime video only plays for about 5 minutes and then it stops.
A: Windows: Open your QuickTime? Player.
Click "Edit -> Preferences -> QuickTime? Preferences".
Under the "Advanced" tab, In the "Streaming" section, change "Transport Setup" from "Automatic" to "Custom".
The port number should be 554, and the Transport Protocol should be set to "UDP".
Router: You also have to enable UPNP (so that it forwards port 554 traffic) if you have a router at home.
