I've forgotten everything I ever knew about copy protection on DVDs. (BluRay disks and UHD BluRays use versions of HDCP, a uniform standard, unlike DVDs.)
You may have difficulty finding a free player that plays copy protected DVDs. This one may work: https://www.winxdvd.com/dvd-player/?AFFILIATE=120043 It's free. As far as I know, the main bad thing about the software is that it'll constantly try to sell you other software from the same company.
