I've noticed that if I set my MBP's keyboard light to turn off at any time greater than 30 seconds, the light will never turn off when watching movies. I like having my keyboard light set to turn off after 1 minute of inactivity, since any lower than that causes it to turn off and on while I'm reading a web page or whatever, but then it never turns off when I watch movies. Kind of annoying having the light on constantly during a film. Does anyone else have this problem? I guess I could always turn it on and off manually, but that's such a pain when this feature should work properly.
