What a great title for a thread!
Anyway, here's an odd problem. I'm on a Mac, with Leopard. I downloaded the DivX player and the Reefer Madness demo to see how well it all worked, When I started the demo and pushed Play on the DivX player, nothing happened save for an extremely loud, harsh buzzing noise that stayed at the same volume no matter what my computer's volume was set to (except for 'mute'). Nothing came on screen - the player stayed black.
Has anyone else experienced this kind of problem? I'd really love to download these videos, as finding the physical copies can be difficult.
