Export .mov with alpha channel

[SIZE=1]i’ve created a flash movie of a symbol with actionscript animation. i’ve sucessfully exported the flash file as a quicktime movie that is also animated. the final problem now, is that although i select alpha-transparency during my export, and have no background in my flash file, when i import that .mov file into third party software, such as Final Cut Pro, I don’t have the transparent background i want, but a white background.

Any thoughts on how to properly export a quicktime movie from flash 8 but have no background when i import into 3rd party software, like Final Cut Pro 5?

here are my files:

**animated quicktime movie
original flash 8 file
Thanks for your help!
