How to change duration of pics but not of the videos

Hi,

I´m getting crazy. I created a slideshow and need to reduce the duration of all pics. When I do it with Cmd+A and Parameters Fotomagico also changes the duration of all videos, which is completely stupid. I even tried to lock/protect videos, but even then the duration of videos is changed.

The option in the slideshow assistant to change the speed does´t work anymore.

Please solve this because nobody wants to change the duration of a video. That is given by the content and it makes no sense.

Or please give us an option to only select video or only select pictures. That would help a lot to make global changes when a slideshow is almost ready.

Regards
René
