Hi and Welcome!
provided you have an older drive that is supported by MCSE or the Patch Utility, you can download and modify the firmware using a Windows environment. A virtual installation is sufficient for that job.
The modified firmware can then be flashed to the drive hardware using Samsung’s flasher for Mac. Please read the FAQ (see my signature) for details and don’t forget to check Samsungodd.com website for further information.
Of course, there is always a risk to kill the drive.
If you are into software only, then have a look at VLC. This software is not known for checking regional restrictions (but your OS might do that).
