Anya

So I got my new computer the other day. I really like it, no problems so far, except it uses a different program than my old one did to play movies. I don't quite know how to make this new program work, but basically when I play anything that's in widescreen format instead of understanding that my computer actually has a wide screen, which it does, the thing automatically puts black letterbox bars on all four sides. Now, the screen on this computer is bigger than the one on my old computer was, but it isn't really big enough to watch a movie with letterbox bars all around it.
Help?

Other than that, I really like the computer. It's name is Anya, which means "The Inexhaustible" in Sanskrit. Hopefully this one will last longer than my previous laptop.
