The manufactoring company is Sansung. It's really frusterating! Any help at all? I recently purchase a regular DVD "Endless Love" on Ebay. The disc is from Thailand.
I've read the manual and googled. nothing...
I wouldn't change it if I were you. They only let you do it X number of times and then you're stuck. Sadly I think you're stuck. It would probably be better to just buy another copy in Region 1 and make sure you have the right region in the future. Or you could buy a player that plays PAL, but that's kind of a waste of money for one DVD and you'd have to get it from out of the US.
