I am glad to tell any Mac users like myself that the webcast works great on a Macintosh.
If you click on the link at fightingsioux.com, the game will load into your QuickTime player. You do have to hit "play" to start it though. Also, go into QuickTime preferences and under "Streaming" set it to match what your streaming speed is. (If you don't know it, check with your ISP.) I did this tonight, and my video quality improved greatly.
