Converting to Quicktime movie

Musical timing is critical with my slideshow. As a result, the display and transition timing is veraible from frame to frame.

When converting to Quicktime movie, the timing is way off. Lags behind the music by about 2 seconds.

Don't seem to get a chance to correct this when converting.

Would appreciate any help with this one. 😀

Using Keynote 09 version 5.3

Many Thanks 🙂
