WMA files in audible folder

[Gaurhoth]

Trying to drop a couple unprotected WMA files into the Audible Folder to take advantage of the automatic bookmark feature (that does seem to work for MP3's).

But the unit doesn't seem to show the WMA in the Audible Books list. I can find it and play it from the Folder Browser.

Can anyone else confirm or am I doing something stupid in my post-christmas haze?

Just a note to confirm that protected WMA's also don't show up when put in the AUDIBLE folder. Disappointing since I can download protected WMA Audiobooks from my local library's website... but without the auto-bookmarking capability, it makes them far more frustrating to listen to on the pilot.

Hope to see this added in the future.
