Can't see movies on rev site

[Kaveh Bazargan]

I am trying to look at the tutorial movies on the runrev site. I am using
Tiger on OS X, and Quicktime Pro 7.0.1. I have downloaded and istalled the
Ensharpen codec, but I hear only sound. There is no picture. I have tried
looking through Revolution Online, but same problem.

Any ideas?
