I started having this same problem just after I installed Pinnacle video
editing software. I don't know if it is the vid software that is to blame,
since I didn't go searching for any avi files on my new computer prior to
installation.

It (DEP) happens everytime an .avi thumbnail tries to be displayed,
including the preview thumbnail when customizing any folders holding one or
more .avi files.

I use the workaround of changing all my video folder options to "document"
instead of "video" and only use "list" in Explorer, but DEP still hits me
when I navigate into a previously unrecognized folder holding an .avi.

I'm just gonna turn mine off until MS fixes this one.

VonGraff,

One of the Multimedia Codecs is probably causing the DEP crash. Insvestigate
the third-party MM Codecs using this utility.

MMCompView v1.10 - View installed Codec and ActiveX filters and enable /
disable them:
