I originally uploaded the WMA file at work with JEmplode (I can't install EMPLODE there) and the file showed up as invalid format when I tried to play it.
I ran Emplode at home (on W95) and it apparently fixed the file format problem (and loaded the WMA meta data when I made the RioCar/PC/RioCar roundtrip).
The last comment, under the ---, was that JEmplode runs well at work, but I can't install/run Emplode - Lite whining that Emplode requires admin privleges to install, JEmplode doesn't handle WMA files well yet, and most importantly - they went to a much more secure admin password scheme for our NT boxes at work.
