Applications :: Exporting To Quicktime From Keynote - Video Playback Stops?

I am running a Macbook 2.4GHz with 4GB of RAM and Snow Leopard.

I have an issue using Keynote 09.

I have created a presentation that has a m4v video playing in the background.

The video was the first thing I put in and was just placed on the slide and set to play when the presentatation starts.

The video starts at the beginning automatically and plays for the entirity of the presentation. The presentation is only 2 mins long. Over it are a number of different words all with various animations. There is also a music file playing in the background.

I have then recorded the show with manual timings and now when I play it in Keynote it runs smoothly from start to finish. The video continues to play and the transitions are smooth.

HOWEVER, when I then try and export the presentation as a Quicktime file I encounter a problem. The video starts initially at the beginning of the presentation but the minute any other animation kicks in the video freezes and does not restart. I have tried a large variety of export settings but to no avail. I have also spent time trawling the internet to try and solve this problem but no solution found.

It is very frustrating. I need to export it because I need it as a movile file rather than a keynote presentation.
