I have a movie to which I added music. I noticed that after it played the first time, each consecutive time it played, the music was no longer in sync with the movie.

I finally saw the problem...when I increase the size of the movie by using percentages, the movie slows and therefore the music is no longer in sync. It works fine when I use pixel size.

I have tried adding the music several different ways, but it doesn't matter how it's done...as soon as I change it to a percentage, it slows down.

Am I doing something wrong or is it normal for it to slow down when increasing the width and height?
