    I have a problem with a .wmv file. When I play it in QuickTime or VLC, I hear audio only, but no video. I have the latest Flip4Mac plugin and have no problems playing other .wmv files. The first time I played the file in QuickTime, as was directed to the Apple QuickTime components web site ( because "Additional software is required by QuickTime to playback this media...". But I see no plugin on that web site that would be applicable.

    I would be grateful for any ideas as I want to purchase educational videos from this vendor, but can not if their files won't work on a Mac. The 43MB file can be downloaded here for testing:

    I run 10.5.6 on an Intel Mac.

    I get the same problem. It's probably some unusual codec, you might try talking to the vendor to see if they can tell you how the video was created and compressed.

    Try downloading and installing Perian (Quicktime Plugin), and see if that solves the problem, if not it is probably a badly encoded file.

    The most recent version of Windows Media that Flip4Mac can handle is non-DRMed WMV9. Your video sounds like it is WMV10 or WMV11. Nothing on the Mac handles WMV10 or WMV11.

    Thanks you guys for your replies. I have Perian installed already, makes no difference.

    The company says the .wmv files were produced with Camtasia Studio, if that tells you anything?

    On a VMWare PC I checked the preferences of the file, and it appears to be WMV9:

    Any other ideas?

    What does the QuickTime Player say the codec is?
