Oh something else that can help with streaming.
1. After it starts, right-click on the movie application and go to options/preferences/???. If there is something pertaining to ram or buffering, set it to a large number (assuming you don't have hard drive limitations).
2. After it starts, pause it and wait 15 minutes. With many streaming applications it will continue to download while paused. Then when you watch you won't be interrupted.
