Explorer causing 100%/High CPU usage on mpeg files

When I run explorer and have a directory with mpeg files in it, if I select the file
(even right-clicking to rename), all of a sudden my system (P4 2.4ghz) begins to
CRAWL. If I have performance monitor running, in about 3 seconds it will show explorer
using up 100% of the CPU cycles. After about 30 seconds, the system comes back and
everything is fine (if I manage to finish the rename, for instance, the keyboard
is slow to respond, but I can get through it, and after the rename the system will
still be slow for another 20-30 seconds). I've searched here and I'm using DMA (this
is a Raid 0 array). I found a "tweak" on the web about explorer and AVI files slowing
the system down, so I removed the specified registry key, but no change. This is
a fairly "fresh" system, and has been going through lots of XP "updates" and it appears
to have begun after one of these, but unfortunately I cannot be sure. Would really
appreciate any insight, it's driving me nuts.

No, I've killed all the services. That wouldn't indicate why it happens as soon
as an MPEG file is just HIGHLIGHTED (not loaded or run, mind you) in explorer. XP
explorer is doing something with that MPEG before I've even asked it to do anything.

I have the same problem. I believe it is being caused by Explorer trying to generate
thumbnails for the mpegs. I have had to change my view settings to something other
than thumbnails. Once I have done this, the problem has gone away
.
