Any suggestions fellas? Replies should be on a basic level - turn on the PC. Plug it in stupid.... I have already sent this movie back to the vendor as unplayable. Yes it does play in a 4k TV player.
Thanks.
MakeMKV says that "the volume key is unknown for this disc"?
MakeMKV produces an AACS .tgz dump file whenever you try to open a disc for which the key is unknown, and will report that the dump has been created. Email the dump file to svq@makemkv.com.
