I just started using Blu-ray Copy. Full Disc Copy to BD50 in .iso form appeared to be what I wanted: a complete digital backup version of my original discs. I played them successfully using VLC, and all the menu options were there. Then I discovered the 1:1 clone to .iso option. what's the difference?

Clone: Make perfect 1:1 Blu-ray clone.
Full Disc: Make perfect 1:1 Blu-ray copy or you can save space by choosing to remove HD audio or compress to bd25
"Full Disc" means all Titles on the disc are copied, but they may be compressed. It is not a bit-for-bit copy like Clone mode, which cannot be compressed and requires a disc the same size as the one you are copying.
