Data Execution Prevention!!!!

Hi guys
I have created a very nice animation (for me anyway) but good ol'
Microsoft won't let me play it as it is dangerous or scary or something
so I get a Data Execution Prevention followed by termination of WMP10.
My mate can play it on his Mac no problems. When I have done some
hunting there is the suggestion that it is a CODEC issue but I have not
got a clue where to start. I have so far used the MS Codec and the
Intel one during the render process. As this takes 30 minutes a go I
don't want to have too many plays.

Cheers for your help

 

Render to full frames uncompressed. Take this image sequence into a
program like VirtualDub (http://virtualdub.sourceforge.net) and edit
your animation to length, then compress to any codec you like and save
an AVI. This way you can come back, change the codec and save out a
different version easily. The Indeo or Cinepack codec should be
installed on most people's systems, but for better quality and
compressability, you should use a format like MPEG-4 ASP or H.264 and
provide the codec to your users, or a link.

Windows Media Encoder should also allow you to compress a series of
still images into WM8/9 and most people have a newer version of Media
Player installed.
