Exporting to windows media player

Have tried with no luck to send a clip generated in FC5 to an associate who has to open it in windows media player. I export using my flip4mac program but when he tries to open it it plays for about 5 seconds and gives the following error.C00D1199: Cannot play the file
Windows Media Player cannot play the file. You might encounter this error
message for one of the following reasons:

a.. The file type is not supported by the Player. For a list of file types
(formats) that are supported by Windows Media Player, see Supported file
types.
b.. The file type is supported by the Player, but the file was compressed
by using a codec that is not supported by the Player.
c.. The file type is supported, but you are trying to play it in a way
that is not supported by the Player. For example, you might have tried to
drag a DVD file with a .vob extension from a DVD to the Windows Media Player
icon. Or you might have tried to open a .vob file by clicking Open on the
File menu.
d.. You are trying to play one part of a multipart file. Use a newsreader
or other program to combine the files, and then try again.
Error ID = 0xC00D1199, Condition ID = 0x00000000
