I am getting a streamed movie at 300 kbit/sec where I am, so I know there is no problem with streaming (as well can you say Akamai!).
If you open the 4.x QT player and choose from the fav drawer and still can't see video you may have your settings incorrect. Perhaps a firewall in the way (like me). So you need to allow for streaming in the 80 or 8080 port. Simply use the auto configure button in the quicktime settings to set it up.

Macintosh fans, on the other hand, may note that cockroaches are far more numerous than humans, and that numbers alone do not denote a higher life form." (New York Times, November 26, 1991)
