Haven't had my Media PC very long and this is driving me nuts. It used to
find my .avi files just fine; I put a shortcut into the "My Documents\My
Videos" folder to the DivX folder where I was storing them on another drive.
It found them and played them.

Then, I installed TheaterTek and the MCE addon "My Movies." Reset some file
associations to make TheaterTek the default player and moved each .avi film
to its own folder so My Movies could inventory them. Now I can't get MCE to
find any of the .avi files, even if I move them back to where they were
originally. It keeps erroring that there are no compatible video files in
any of the folders.

Apparently I've screwed up some settings/registry entries. I'm no novice
with computers and feel very comfortable using Regedit, so if anyone could
kindly tell me where to look to fix this, I would be most appreciative. I
don't want to have to re-install MCE, really I don't.
