How Can I protect my swf files from decompiling / saving

Question

I have navigated through the internet for a long time now but
could not find the solution to my problem which is "how to protect
my swf file from decompiling/saving"?
I know that it CAN BE DONE and here is an example of a file
on the internet that cannot be saved or decompiled using any
software that I have come across (ie:SOTHINK decompiler, saveflash)
http://www.3dinternet.com/video.swf
Any help? any hints ?
Thanks

There is no way to protect your SWF from decompiling. Any
commercial
software on the market can be decompiled -- including the
Flash authoring
tool and Photoshop, for example -- which is why softare
generally ships with
an end user license agreement (EULA) that expects you to
agree not to
decompile or reverse engineer your purchase.
Most Flash content (other than RTMP requests for video, for
example) are
HTTP requests, which by nature means the content is
downloaded to your hard
drive, just like HTML documents, CSS files, JPGs, and GIFs.
Your browser
requests the files, downloads them to your hard drive, then
displays them
from your local copy.

What you've seen, then, is merely the result of software
that uses
unknown (to you or to your sofware) encryption/obfuscation
algorithms. Keep
trying, and you'll eventually nail it.
At best, you can use obfuscators to temporarily deter a
certain segment
of the decompiling-inclined population.
