I've been encountering a very big problem lately. I recently started gathering anime footage for an AMV that I'm creating, but everytime I export the footage from VirtualDub or VirtualDubmod in the Huffyuv compression codec, the resulting file screws up my computer. Whenever I try to open the folder I save it to, I get this message:

and the screen closes itself. I thought it was something I did or didn't do in the diagnostics, but even files that I'd saved to a disk over a year ago in Huffyuv (I recently underwent a computer reformat) refused to load and crashed the screen too. I know that it's Huffyuv that's doing this because whenever I try Uncompressed or Xvid it doesn't give me the error.
So what should I do?
