Avid Codec

hey guys...

i'm trying to open some quicktime movies in WINDOWS XP that were exported out of (AVID EXPRESS in a MAC)...
when i open the file it gives me a white movie with nothing else and gives me an error message "required compressor could not be found"

does anyone know where i can get a codec that will let me play quicktime videos exported from MAC AVID EXPRESS

thanks :)
