I’m trying to use pixelfumes reflection class ([http://pixelfumes.blogspot.com/2007/03/reflection-class-v3-with-source.html](http://pixelfumes.blogspot.com/2007/03/reflection-class-v3-with-source.html)) with a custom videoplayer.

On everyting else the class works fine but with video it apperently needs a crossdomain policy file. After searching and reading up on it i have learned what the file should look like and how to load it with LoaderContext. But there i’m stuck.

I simply just don’t understand the thing completely.

No matter what i try it keeps saying: SecurityError: Error #2123: Security sandbox violation etc etc…

I know that others have made this work but i just cant find any examples on how to actually implement this crossdomain policy file thingy with pixelfumes reflection class. If someone can point me in the right direction i would be very grateful.
