[SOLVED] Question about MP4’s

I use Windows Media Player 11. Whenever I download a movie I usually click on it to make sure it is the right .avi and it downloaded okay. Whenever I download an MP4 for one of the tablets and click on it, I get something that looks like this:

Am I missing a codec or something?

Answer #3
Thanks guys but I found out we are all wrong. I feel like a dummy! I just needed to right click and check on “open with” and check the box next to Windows Media Player. I didn’t even think of it. I wasn’t used used to working with a tablet and thought it was connected to that.
