This was back in like 2005 and 2006, but I had issues with my 1000MHz TiBook playing it. This was on fresh installs of both 10.3.x and 10.4.x, both with and without updated flash installs, and in different web browsers of the time (OmniWeb, Firefox, Safari) -- sometimes I just begin to think that there was something pretty bad wrong wtih that specific machine.
