Problem playing video file with WMSpeech encoded audio in Creative Vision:M

[tp104]

I tried to play a WMV file in my Creative Vision:M and it says that the audio format is not supported. I check with GSpot and the file type is ASF (.WMA/.WMV) encoded with WMSpeech codec. I take that it's different from WMA codec even though it's supposedly encoded from a wma file. Anyone know how to get this to play on my creative player?

Thanks,
