Different codecs can make video support interesting, even when the container format is supported. VLC has long been my go-to video player. They've put serious effort into supporting every video format out there without relying on external libraries. Give it a try at videolan.org. If it can't play it, then there's a good chance that the file sent was corrupted somehow.
