Loop video but play audio once only

Hi there,

I need to create a flash video for a website of a product rotating through 360 degrees - looping seamlessly. This will be 100 frames long. I then need to add a 500 frame voice over.

I need to optimize file sizes so what is the best way to tackle this?

Is there a way to loop the video with actionscript but not the audio? i.e. rather than extend and repeat the video phyiscally in the timeline inlind with the audio length - as I assume this will increase the file size?

I’m using flash cs4 and only have basic knowledge of flash.

Any help or actionscipt advice would be most appreciated.
