Review posts #25 & #27 in this thread:

Then review Posts #29 & #30 in this thread.

Where are the Most Recently Used Lists?

Consider installing the software linked in Post #29.

Other than that - move the contents of the problematic folder onto an external drive and disconnect it until you can figure out the problem video(s)

I've had the same problem. What solved it for me is to change the folder view from "medium icons" to "list".
The problem is caused by missing thumbnails. Windows is trying to recreate them (unsuccessfully), that's what throttles the CPU.
