MovieSnapshot
http://www.cd2html.de/moviesnapshot.en.html
Using Microsoft Windows XP or 2000 it is normally not as easy to create
a thumbnail image out of a video. To exactly doing this I have written
a small application called MovieSnapshot. With MovieSnapshot you can
for example get a simple preview image for each video from a CD video
archive. You can simply drag and drop a video out of the Windows
Explorer on MovieSnapshot to open the video. After opening the video
look for the right point to make a snapshot of. Then you only have to
save the result - and that's it. MovieSnapshot suggests the video file
name plus the extension ".jpg" as default for saving the snapshot.
It supports all installed DirectShow video and audio codecs.
MovieSnapshot is freeware.

When you want to take a few screenshots from a movie clip in Windows
Media Player, press PrintScreen, paste it in an image editing program,
and you get a black screen. The reason for this is due to Hardware
Acceleration being enabled. But you can turn this feature off.
In Windows Media Player, go to Tools > Options > "Performance" tab.
Move the Hardware Acceleration Slider to None.
