To check the machine’s installed wmp codecs:
Go to WMP, press alt to get the menu, select Help->About… then click Tech Support Info. It will generate a report which amongst other things lists all the supported audio and video codecs.

Do this on both machines, Hopefully this should reveal the missing codec.
