The only two Mac QuickTime "codecs" you need in OS X are Perian and Flip4Mac. You will be able to view most video files that are not copy protected.
Now is this video copy protected? VLC will play most any video file but if the file is with Windows Media copy protection you need to re-encode that file to mp4 or something along that way, in Windows.
