Tv will not display slideshow!!

Hi everyone I just purchased the correct adapter for my macbook to run my slideshow on my tv. It displays the desktop/background of my mac, however when I start the slideshow with the frontrow remote or from the mac itself I get a blank screen. I could not find anything in display preferences ( I am under the gun as I have guests coming over soon to see our fiji vacation pics.)

Many Many thanks!!

Have you tried to play the slideshow from iPhoto instead of Frontrow? Frontrow has some issues...

If the picts are already in iPhoto it should a few minutes at most.
