There could be a number of causes that will result in this problem.
The simplest is this: Is the folder customized to display "Pictures and
Videos"? Do this by right-clicking on the folder, then selct
_Customize_. Under _Use_this_folder_type_as_a_template_, select
-Pictures and Videos-.
Another possible cause are codecs. Have you recently
installed/uninstalled codec packages? I've had the experience also that
even if the file can play in Media Player, I didn't always get
thumbnails. I rooted my experience down to codecs, and when I removed
all codec packages, and re-installed a single package (for x64), my
thumbnails returned.
I currently use this codec package: 'Vista Codec Package Homepage'
