DVDFab 9.2.2.6, other blu rays rip just fine. Discs 1 & 2 from Harry Potter 8 film collection blu ray pack have audio at least a half second out of sync. Have tried multiple settings multiple times, but no luck. Ripped Penguins of Madagascar right before this, with same settings, and it was perfect. No other BD or DVD software installed. Unsing Windows 10, 64 Bit, Intel Pentium CPU G620 @ 2.60GHz. 8.00 GB RAM. This is a clean install of Windows. I do not use this PC for anything else but DVDFab. Standard DVDs rip perfectly. Any help you can give would be much appreciated. Thanks!
