If you are trying to watch any of the GoogleVideo or YouTube videos here and are having trouble, try this:
Press the Pause button on the video control panel and wait while the stream is ‘buffered’ or downloaded in the background. Once you have at least 50% of the video stream buffered, resume playing. The remaining video stream should download while you are watching the first half. If that doesn’t work - then all I can suggest is to change your broadband plan or don’t watch online video!
