When I try to play a movie from a cd that was made by a friend, some of the movies will not play. I can hear the sound but can't see the pic. It says, problem downloading codec. What can I do to play these clips? Please someone help.

The video I'm trying to play is called ----video clip V2--- I can't find the codec for it. Any ideas?
