Hi Warren
Tx for posting this. This might be very helpful to other users as well.

Regarding the last part of your message about silverlight having to be installed that is correct.
Like Flash, Silverlight is a Browser Plugin which has to be installed to use silverlight applications.
But the same is true for FirePlay. In case of FirePlay it is the Flash runtime environment.
You probably had flash already installed from before as it is used on quite many websites.
