Corrupt .MOV & .MPEG4 file. Any help?

So I have a friend who is working on a project and received two files. One is a .MOV and the other is a .MPEG 4 file. When I try to open the files I receive an error telling me there is no stream of audio or video. So after messing around I found out the videos have a codec of WMV for video and WMA for audio. This is weird. I did some research online and got no where. I don't think that those codecs are supposed to be used in a .MOV file. I've tried opening the files in quicktime, windows media player, vlc, premiere pro and I've even tried uploading to youtube in hopes of downloading the video offline. So I can only assume that the video is labelled wrong and I need to replace the .MOV portion of it. How do I do this? Or what other methods should I use to fix this?
