It seems the dsound driver is not able to do a fallback to a supported
format and probably your sound card driver like most today has only very
crappy waveOut support.
Try adding "-af format=s16le" to the commandline.

MXFlib supports files that are far, far outside the specs, and many
tools that create MXF files are still based on very early drafts.
Some bugs of even the products from the bigger players were found with
the help of MPlayer's demuxer.
Please upload a sample to ftp://upload.mplayerhq.hu/MPlayer/incoming if
you want us to see if we can easily support it.
Same for the wav file in case the tip above does not help.
