Podcasts mixed in with music

On my old clip, there is a separate subdirectory for podcasts but on my newer clip the podcasts are mixed in with the music files.  When I look at the clip using Windows Explorer i can see the separate podcast sub directory but not when using the clip.  The troublesome clip is v 01.01.18A, my old one that works well is 01.01.32A.  Is this possibly related to being backlevel on the firmware?  When I try to update the firmware I get errors.  Other than the subdirectory problem it seems to play satisfactorily.

Try updating the firmware manually.  See the sticky in the forum. 

Did the update and it solved the problem - Thank you.
