My father's new laptop has the following inbuilt DVD-drive:
Matexcretory substancea DVD-RAM UJ-8205.
There are two region code switches left.
How can we make it region-free? We watch a lot of foreign films, and all my opera DVDs are imports, and so on. I can watch them on my DVD player, of course, but my father and mother want to be able to watch whatever they want to watch on that laptop computer.
I've done a search online, and while there are apparently quite a few options for most DVD drives, this one is tricky.

Regional restriction (RPC II) works by not revealing the title key on CSS protected discs IF the region code of drive & disc do not match. Usually this brings up prompt to change region, but you only get to change drive five times before firmware locks it onto last region (Nero drive info tool will tell you present state). Regional free software works with a brute force attack on the scrambled sectors containing the title key. Unfortunately Matsuexcretory substancea (Panasonic) have exceeded the MMC standard on this drive by not allowing even the scrambled title key to be read. Few if any other drives behave this way which is why the software manufacturers often claim it will work with ALL DVD drives.
