I've produced a slideshow where I manually move from one image to the next (to allow for ad hoc commentary) and then an AV show commences. However, both in preview and as an Exe file as soon as the AV show starts it freezes. I have tried publishing it as a HD MP4 but then it loses the ability to move manually from image to the next and shows it as one continuous AV Show with auto transitions thereby losing all control. Help would be much appreciated.
