A few months ago I bought the complete #Buffy the Vampire Slayer box set from ebay. Fairly reasonable price. It came all packaged and nice and had extras like the 20th anniversary comic and a coloring book, a fancy cardboard box for all the DVDs, etc. Then I went to rip the discs for my backups (and to stream to myself on Jellyfin) and got a warning from each disc (from MakeMKV) that they were made with a common burning program used by pirates, not by a factory process.
How likely is it that this was a false positive? The discs all seemed to rip just fine. If these are pirated, then holy shit the pirates did an amazing job. They must have some serious equipment like whatever it takes to make that fancy box and the color-printed info inserts, beyond just making the DVDs and printing them to look official.
