Control Point Podcast

This isn't really a movie or an app, but I think it fits the best here. There's a group of guys (and sometimes a girl) that does a TF2 podcast every week. It's called Control Point. Link: [You must be registered and logged in to see this link.]. Their earlier episodes go over each class and tactics for them and all the Valve maps and some good community ones. They can be downloaded for free on iTunes, even if you don't have an iPod.
They started when TF2 came out, and even if you don't really care for the tactics and information, it's still really cool to listen to everyone's reactions to the updates, in case you weren't there when they happened. They're also pretty funny. At least check it out, it certainly helped me a lot.

See ya on the server!

Haven't heard of them, but I wil check it out. Btw, I made the link clickable

I've been a member for over two years, It's a great podcast. New listeners should re-listen to the oldies due to so many inside jokes.
