Fade movieclip to transparent

[Jakobdo]

Hello,
I have made a slideshow from this tutorial:
http://www.thetechlabs.com/tutorials...show-with-xml/

I have added a reflection, and it works just great.
But i would like to make the right and the left side fade to transparent.
I have tried to make a little demo here: http://codebreaker.dk/flash/

The first movie looks good, but only because I have faded from nothing to black and the background is black on the home page.
And as you can see, the movie does not look that great, when the background is white.

I found this link: http://blog.soulwire.co.uk/2008/12/1...arent-bitmaps/, but I can't figure out how to implement it into my already "working" slideshow.

Anyone ?
