1. Out of curiosity: DVD Regions are usually only used for Video-DVDs (The Region code is stored in the file "VIDEO_TS.IFO" [table "VMGM_MAT"], byte offsets 34 and 35), but I think they could also used as part protection of other DVDs (e.g. games). I imagine it like this: A protection program would check the Region of the drive the DVD is inserted in (like the program DVD Region Info), and if the drive has the right Region (the result of the check is compared to a value stored in the program), the software runs. Is such a protection imaginable? Would AnyDVD bypass it, or does it only work for Video-DVDs? (YES, e.g. with autoreset firmware it should be possible to bypass the protection, but as I said, I am asking out of curiosity. Or is there a way to recognize autoreset firmware? ) 2. In Blu-ray discs, only the Region (and sometimes the Country Code) of the player/player software is verified. With some free software (e.g. VLC, PotPlayer), Blu-ray files can be played, but they have no option to set a Region or a Country Code. Does this mean that you can watch files from Blu-ray discs from all Regions, or that Region-protected Blu-ray discs will not play at all with them? Thank you in advance!
