when trying to play a downloaded version of Advent Children, i get the message that i don't have the appropriate video codec to see the video... but i can still hear it

It said i need the codec H.264 and all i use in Windows Media Player

Can anyone help?

Ok, where did you get this file from??

I just went to the Advent Children site, and what they have to download is a quicktime file. And it says you have to have quicktime to see this file.

I clicked on links that took me to another advent childern site and saw quicktime embeded movies in a flash webpage.

Do you have quicktime installed?
