Which player won't work?

The Amicron Player won't work as it is an .exe which doesn't run on Macs as it's Windows based.
You can install a program called Wine which will allow you too though.[http://www.winehq.org/]

Have you used the Walkthrus:

Won't Work:
Download One Self-Extracting File

Should work:
Download Just the Video Files Manually

Make sure it is the MP4 and not WMV, unless you have Flip4Mac http://www.telestream.net/flip4mac/overview.htm

Now with the files downloaded you can play them in QuickTime etc.

(The Online Theatre should work fine.)
