it would be nice if there was an option to post decrypt bluray disks.
that would copy the contents to the mac and then decrypt it on the mac rather than loading a packet from disk and decrypt and write to hard drive.
since bluray disks are not like dvd (as far as i know of) where there bogus sectors used to confuse the drive and cause a copy failure it should be safe for you to copy the data to the hard drive and decrypt if needed.
the big advantage is for we users with slim line drives that are usb powered where the drive is near the starvation point for power and can cause bad reads and the sooner the data can be extracted the better
also the exclamation point icon for the finished status i think could be replaced with something that means success like a check mark or thumbs up would work better.
exclamation point usually means warning and would be better fitted to something like it did backup but there may be errors so please use with care.
