Hi, I'm a Mac, but I won't play Apple's Videos

So you know those cute Mac ads? With the cool mac guy and the silly, stupid, stuffy Windows person (it's really about what OS the PC is running, not the hardware). Yeah, well, I'd heard about them, but I don't watch much TV these days, so I hadn't seen them all and they do seem cute. No problem. I have a Powerbook laptop. So I go to the Apple site, find the videos. I can hear them but not see them. Best I can tell, my OS 10.2.something--I don't know what stupid feline it's named after--doesn't seem to be able to get whatever this week's codecs are to actually play the darn videos.

I'm a Mac. I'm two years old. If you want to watch videos about how cool I am, you'll first have to fork over money for an OS upgrade.
