It happens on Youtube and in Windows Media Player. Quicktime, oddly enough, isn’t playing any videos at all; I never actually used it for anything before. (This may be a codec issue. I’ll fiddle and see if I can get it to work.)
Update: Apparently, Quicktime for Windows is incompatible with Divx/Xvid codecs, which is why I can’t play my .avi files in the Quicktime Player. There is a codec called “3ivx” that is supposed to work, but the creators charge for it.
Advice for a similar problem is here
The problem has persisted through several video card driver updates. :(
Does it do this regardless of the software playing the video e.g. YouTube and VLC or WMP or XMBC or whatever you use to play your videos?

For YouTube, try right clicking, choose ‘Settings...’ and uncheck ‘Enable hardware acceleration’. Any change?
I finally found a fix.
Yes. That gets rid of the black screen. Which means my video card is doing something funny when switching modes.
