I had this problem too. Audio on WMP just suddenly stopped working. I was able to solve it using Audio MIDI Set.

Here’s the solution, from Apple’s website:

http://docs.info.apple.com/article.html?artnum=300832

Solution
1. Open Audio MIDI Setup (/Applications/Utilities/), then check the Audio Output setting.
2. Change the Audio Output setting to 44100.0 Hz.
3. Quit Audio MIDI Setup.

Why does this happen?
Some third-party audio applications may change your computer’s audio output setting. In fact, if you use the third-party application again after applying the above solution, the issue might occur again. Observe changes by watching the settings in Audio MIDI Setup before and after running a third-party application you suspect might be causing the issue. Contact the manufacturer of the application for more information.

Sometimes the error message “This file may not play correctly because it was compressed by using a codec that is not supported”, occurs when the Mac’s audio settings get messed up; primarily, the file com.apple.audio.DeviceSettings.plist may have gotten damaged. It’s at Macintosh HD/Library/Preferences. Trash it, restart the Mac, then open the Sound prefpane and check its settings–make sure that the appropriate hardware for Output Device (and possibly Input Device too) has been selected. Sometimes the Sound prefpane can’t properly set these settings, but the application “Audio MIDI Setup” can do the job; it’s at Applications/Utilities.

Sorry folks. Dunno why Macs don’t have (or can’t get) the codec.

I recorded it using straight, “standard”, Windows Media Encoder.

The Video codec is “Windows Media Video 9 Screen”

And audio codec is “Windows Media Audio 9.1
16 kbps, 22 kHz, mono (A/V) 1-pass CBR”

Same here, Peter. None of your videos work on Macs. And the window automatically resizes itself to full screen and runs off the side of the monitor (even though I have a 22″ and a 17″ monitor side-by-side)

The error reported is: “This file may not play correctly because it was compressed by using a codec that is not supported.”

Seems it is a Windows only codec, probably chosen by default in your recording software. I can play all types of WMV and WMA files on other sites.

Hope this helps.
