Problem with video when not playing through media player

Hi

I recently have come across a problem with video files. I first noticed it on a game (midtown madness 2) which starts up with a microsoft movie file but now in its place are diagnal lines and the message “Video not available. Cannot find VIDS:IV50 decompressor."

I also get this when playing (or trying to play) video clips in power point in a presentation... The only time they will play is through Windows media player 9.

Does anybody know why, and how to solve?

Many Thanks

!
