There is a bug in Windows (XP) registry entry
to activate autoload (DVD ...)
In this key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AutoplayHandlers\Handlers\VLCPlayDVDMovieOnArrival
modify the name of the String Invoke.ProgID by delete dot.
(replace Invoke.ProgID by InvokeProgID)
And for other keys ...
Nest regards
