Working now! Thank you everyone for all the help

Thank you, here is the dump from MakeMKV
MKB20_v76_National_Lampoon's_Christmas_Vacation_89BB.tgz

Sorry, I worder that wrong. I'd taken advise given to other and I downloaded and installed Xreveal. It said "The disc key was not found in keyDB.cfg. Do you want to find it online", after answering "Yes" it still can't find the key. Disc Information - Create a dump file Label: NL...

Also tried XReveal and it can't find it online. Anything else I can do help get this one available?
