Converting non-youtube videos to ipod?

Is there a way to convert videos from websites other than youtube so that they can be played on an ipod? I want to convert a video by nfl films (only available at nfl.com due to copyright reasons) onto my ipod. Heres the link:

http://www.nfl.com/videos?videoId=09000d5d808a95dd

If anyone knows how to do this, or they have seen this video on another website, please tell me.
