What is required to play a .wmv file on a MAC OS X 10.6.8?

If it's an unprotected file, the free version of Flip4Mac. If it's a DRM protected file or one containing malware, nothing.

Flip4Mac 3.0.0.126

MPlayer 1.0 rc2

Flip Player 3.0.0.143

Not all of Microsoft's codecs have been licensed to be ported to other platforms, so it's quite possible that you cannot play that WMV in Mac OS X, even though it does not contain DRM. You can try asking for assistance in the Flip4Mac forums:

and they may be able to help. Otherwise you'll probably have to use a Windows system, either on your Mac or another computer, to view that video.

Regards.
