I got a reply from the helpdesk which was the solution : Joost, It sounds like you are using an offset for one of your audio tracks in your soundtrack. If this is the case you need to use this work around below because ProShow Gold has issues with positive offsets. First, add an audio file to your slide show just before the track with the Offset. Second, set this new track's "End Time" to the Offset value of the original track. Third, remove the Offset from that original track and set the volume of the new track to zero.

Mine also had some glitches but i found ways to work around them. I only do the iso files.I stopped using 500MB pics. the audio got choppy, in the audio edit screen. Ijust live with it. once i burn to dvd it sounds fine.
