I tried to copy Rambo Last Blood DVD region 1 on my desktop, a HP 64-bit running W10 with 2 optical drives, one from HP and one ASUS, using CloneDVD2 2.9.3.6 and AnyDVD 8.4.2.3, and it failed at 97% in both drives. Today, 1/1/2020, I tried it again, using CloneDVD2 2.9.3.6 and AnyDVD 8.4.2.3 on my newer Lenovo laptop, also running W10, and it copied!
