Got a problem playing some videos

[Shaggz]

I just downloaded some Squidbillies episodes because I cant ever catch the damn show on Adult Swim.
Whenever I go to play the files it gives me an error. Ive tried Realplayer, Windows Media, and DivX player.
When I used Realplayer and WM, after the error, I just got audio and no video.
When I tried DivX it gave me more info than just a basic error message...
The video file you are opening includes video data that is not recognized by the DivX Player.

The file contains the following type of data:
Video data: FOURCC code "H264"

You may need to install a new video codec on your computer to watch this video.
So whats the deal? What should I do?
Thanks guys.

There are a few codec packs you can download for free. The Divix codec is a must have.

Hell yeah, that K-Lite codec pack worked, it a ton of options to install, I just chose the playback only setting.
Thanks, I can now watch Squidbillies and loff and loff.

That mega codec pack has just about everything under the sun.
