My copy of the Parasite (2019) UHD (US version OPD: BD_c9fdbd40a4fe) shows a disc size of 93 GB in Windows and AnyDVDHD reports a disc size of 95 GB. However, AnyDVDHD rips the disc to a size of only 71 GB. The ripped blu-ray folder plays fine on my Oppo player. The French version of the UHD rips to 96 GB. I am wondering why there is a size discrepancy between what Windows and AnyDVD report and the sizes of the ripped blu ray folder. I have never encountered this before. It is as if there is some content on the disc that AnyDVDHD cannot see and access. I appreciate any advice you can offer about this discrepancy.
