    No video on my screen. Is this a Mac incompatibility?

    Mostly problems viewing video present issues are not having a current Flash Player. You could try Adobe or even a Shock Wave Flash. The issue may also be that you have not updated your Browser, doing this alone could help. Hope this helps.
