BSplayer Free wont play from external sdcard
 

BSplayer Free wont play anything from external SDcard.
It pops up the message "(0) files added to play queue"

When i copy the files from external SDcard to the internal storage /mnt/sdcard then it plays them from the internal SDcard without problems .

Other mediaplayers (like moboplayer and the stock android media player) play the movies from the external SDcard without problem.

Details
OS: Android 4.0.4 stock on a xoom
BSplayer Free 1.9.150 (from google play)
internal storage /mnt/sdcard
external storage /mnt/external1 [formatted fat32]

Anyone else having this issue?

Do you have full rights to external SD card? (are you in admin user account)
