True, but that is an entirely different 'thing'.
The problem is, that the PS2s DVD-Player (on NTSC-PS2s) simply doesn't decode Video-DVDs, which are encoded in PAL.
The sectorbased scrambling (CSS=Content Scrambling System) and the 'region-restriction'/DVD-Region [which is defined by the files] isn't a problem here...
When the video is ripped from the disc by a program for encoding, the video has to be descrambled (Usually done by the DVD drive).
To be exact,... The Video-Files/Sector-Content (the User-Data-Block in a sector) has to be 'descrambled' to retrieve the Video-DVD-Files (a.k.a., those in 'VIDEO_TS') in non-encrypted form.
The Video-DVD-Files then get demuxed (without file-output of demuxed streams, but still it is somekind of demuxing/'reading the container-file') and the Video- and Audio-Streams get 'decoded' (in this case it is a 'lossy encoding method').
If that happens, the DVD video becomes "region-free".
I've done that before, to get a region 5 disc to be played on one of the region 3-only DVD players I used to use.
Of course, something that will be very great is a piece of software that makes the PS2's DVD player region free.
I know that it's not a hardware limitation, as the first Playstation 2 was *region-free* when the user pressed a certain combination of buttons when using the DVD Player v1.00.
Like I said,... The issue is not in any way linked to it (region-restriction and sector-scrambling),...
