Willum, I believe you are correct.

Doug,

I will send you a zipped file of
one of the .wma songs by email. Let us know if it plays on your MAC

My question...Is it the MAC, or more likely is it the MAC media player that is at fault? I believe the default media player for a MAC is QuickTime. I have QuickTime on my PC, and it does not read .wma files.

So my next question...Can you install Windows Media Player on a MAC, and use that to play .wma files ?
