MPF/DiscImageCreator vs DVDFab for DVD-Videos

I've mostly been using DVDFab for dumping DVD/BR discs and as a test, I dumped the same disc using MPF and DVDFab and the file sizes are exactly the same but only the MPF CRC matches the redump one.
I'll probably use MPF from now on for DVDs but just out of curiosity, what would cause the MPF and DVDFab dump CRCs to be different?

Do you mean when dumping video DVDs/BDs? Maybe DVDFab is patching the output.

I haven't made comparisons with BDs yet but yes, I mean comparing MPF and DVDFab DVD dump CRCs. My DVDFab settings are basically default settings and I use the "Clone/Burn 1:1 Copy" option and under "Advanced Settings", I have "Copy DVD-Video Data Only" unchecked and "Copy Original IFO Files" checked.
For reference, when I dump BRDs with DVDFab, I also keep the Full_BDINFO.[Title].[Date].txt logs just in case.

Does DVDFab decrypt CSS? Does it make DVD-Videos regionfree? Does it remove user operation prohibitions? Any of these would change the checksum.
