Anyone know about streaming .wmv ?

[JethroUK©]

I've asked before without success but:

How do you protect streaming video (.wmv) from being stored (saved as a
file)

I have to make hundreds of teaching aids via streaming video (from my pc)
and i would obviously like to prevent end user from stealing them all

I've been told previously that it can't be done, but many of the streaming
videos on the web are protected this way so i know it is possible - just
dont know how - i would imagine it's something in header that disables
saving or buffering (like .ra file), or maybe something server end

The short answer is that it can't be done. Anything that is sent to a client
PC can be saved, there are plenty of free tools to get around streamed video
save prevention. Quicktime tries to get around it using 2 video files - 1 to
load into the QT control itself, which then loads the actual video in the
background - however even this is relatively simple to get around.

The official way is to use DRM:

The only fool-proof way is to not let people watch it!

No, they just use techniques to make it HARDER for the casual computer user. A
person determined to download a copy can get tools from the Internet that will
copy any format.

on the assumption that nothing is impossible - is there anything i can do to
make it 'harder' (disable save)?

Looks as if an Office newsgroup might also be applicable.

By default, WMP does not cache or allow the user to save streamed content.
Downloaded content is another story.
