Warning when playing wmf-files

[Marcus Zingmark]

I'm getting this frustrating warning while starting wmf-movies from 
Gnome telling me that the file actually is an ASF-video file and it 
can't be opened since this could be a security risk for my system.

This is a message I get often since i handle movies and such from now 
til then so I wonder if it's something I can do to turn of this warning?

Please don't tell me I can start the program I use (vlc by the way if 
that should matter), and open files from there - that I already know. I 
want to get rid of that stupid message ;)

P.s. My quotation of the message might be a bit far of beacuse my 
message comes in swedish and I didn't feel like spending much time 
translating it. But for those that are fimiliar with this message I 
think you know what I mean ;)
