Slideshow transition effects not working (WD HD TV player gen1 - firmware version 1.03.01)

Cannot seem to get the ‘wipe’  or ‘fade’ transitions to work when viewing slideshow. For the ‘wipe’ effect, the slideshow just goes to the next picture without any transition, for the ‘fade’ the picture goes black for a couple of seconds and then the next picture appears.  Has anybody else experienced this problem? Thanks.

PS. I also have a gen2 player that performs all the transitions perfectly.
