When using Rox, xffm, nautilus, gtk file selector from within xfmedia, only one
entry is produced.  It is not playable and does nothing but annoy.  

What should happen is that xfmedia should add all files recursively within that
folder and filter for files it can play, (ie .mp3, .avi, .ogg, .mpeg, etc)

Ideally this list of file formats would be set someone in preferences with a
sane default.
