Thank You for the great module!
I wanted to create custom theme using Views Slideshow and DDBlock. All steps worked thanks to tutorials until i tried to place my own tpl files at /sites/all/themes/[theme]/custom/modules/views_slideshow_ddblock
But my ddblock custom theme didn't show up in Views slideshow ddblock theme list.. until it was named 'vsd[something]'. I'm not sure if it a bug or just something undocumented.
However - problem is solved but maybe that is useful tip for someone else.
