MetaX and Windows Explorer issue (Windows 7)

Hopefully this is the right place to post this...sorry if it's not.

I use MetaX (an MP4 Metadata editor) to add cover art to the mp4 videos in my library. It worked fine until just recently, when suddenly a few videos at random (it least it appears to be at random) showed up as the default "music-note-and-film-strip-with-hot-air-balloon" picture instead their assigned cover art. I opened these files in MetaX, which said that they were displaying the correct cover art. How do I fix this? And why is it only happening with some of my mp4 files?
