My Panasonic digital camera records movies in .mov format.  I don't know why, and I can't change it.  The problem is that Windows XP doesn't show thumbnails for .mov files, which is an issue when I want to look through my pictures and videos with the whole "View → Thumbnails" option selected.  I searched the internet for a solution several months ago and didn't find anything.  I just searched again this morning and found a pretty simple solution, though I'm surprised at how relatively obscure it is and how hard it was to find.  Here's what you need to do: 
  1. Download QuickThumb.dll from here.
  2. Copy to C:WindowsSystem32.
  3. Go to Start → Run and type regsvr32 QuickThumb.dll.
  4. If there's an error, download msvcr70.dll from here and repeat steps 2 and 3.
  5. Go to a directory with .mov files, switch to thumbnail display, and possibly press F5 to refresh.
I can't believe I didn't discover this sooner.  That really annoys me.  And it annoys me that the internet wasn't much help for a while.
