Can you overcome whitelist?

My friend had taken 4 short digital videos that he put onto his laptop. We transferred them onto my Kingston memory stick and I transferred them onto my PC. I was going to burn them to DVD so I went to re-name them numerically so they'd be burned in sequence. However, when I right-clicked on the first video, I had a notification that:

"Windows Explorer has encountered a problem and needs to close. We are sorry for the inconvenience."

This happened when clicking on all the videos.
Anyway, I just dragged the notification off screen and carried on. I then got a message :

"The instruction at "0x6ea6936b" referenced memory at "0x0471c010". The memory could not be "read".

At this point I scanned the videos with Spybot and the results were that 2 of them were clean, one was unknown and the 4th was Whitelisted (md5).

Can anyone advise me as to what is happening with these videos, especially the whitelisted one? Whatever that is!
Also, is there any software out there that can do what is necessary to make the videos normal?
Thanks.

Windows Explorer likes to shutdown if you have the folder set to show thumbnails and your PC's codec doesn't like it. To test, open a CMD window and navigate to your folder and try converting one with ffmpeg:

c:\users\whoever\desktop\folder>

ffmpeg -i videofile.mp4 -acodec copy -vcodec libx264 newvideo.mp4

Then test that with spybot.
