Avi files (divx) can be trouble in xp. there is a fix to let xp behave much
better so it's possible to move or delete large avi files. The obnoxious bug
in XP that causes Explorer to read the entire contents of broken AVI files
before allowing any access to them is caused by bad behavior of shmedia.dll.
To correct this misbehavior in Windows XP, remove the following
registry key.
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{87D62D94-71B3-4b9a-9489-5FE6850DC
73E}\InProcServer32
This will prevent Explorer from loading shmedia.dll in response to file
property queries on these files.
