Windows Media, can't play?

[OldMillXxX]

Just got an email that had a .wmv file attached. Tried opening to a message of Can't play this type of file. Really?? Why can Windows Phone not play a media file of their own?

It may be corrupt, or it is too large to be opened by the phone. I'm pretty sure it's supported by WP8, though. Otherwise, there's Moliplayer.
