I am experiencing the same problem but I would classify it this way....The audio seems to be running at the correct tempo but the video display seems to be the problem. In fact I have the same problem, but in reverse, on the DVD I created. The program runs perfect while creating it but it seems that when the finished .exe is running on some computers, the display processor can't keep up...thus the video runs to slow and the music finishes first. While on the DVD, the video in the svcd file runs to fast and the music ends up going long. In both, cases this is not good. I can't send out computer disks or DVD's. Seems to be a problem with the video stream output from the program. Any idea on the problem, or more importantly, how to get it fixed? Just for reference, I set a list of mp3 files to play during the show and set the slide durations individually so that the music, audio comments and slides all match up to where I want them.
