kk, If you use it I would'nt delete it. But if you dont it's a waste of HD space
(From PowerDVD 1.3 package)
Put a DVD disk in the drive, wait for the light to go off, and run this applet.
It creates a file in C:CLTEST.TXT.
Besides a whole lot of info regarding your hardware and drivers, at the end of the
file you will find info about your DVD movie, namely: Whether the movie is copy protected
(i.e. CSS scrambled) and what region limitations (if any) there are to play that movie.
I have noticed that a lot of DVD's that have a region printed on the back of the case
are in reality region free, or they support more than just one region.
