Hi,

New user here.
I've paid for subscription, even though it says I'm still on trial version.

How long does it take to make a copy of a Blu-ray movie to a Blu-ray disc?
I've clicked main movie, X-Men: First Class, with DTS-HD.

Source blu-ray to Blu-ray rewriter.
Currently it's been running over 3 hrs and it says 15%, task time left 19 hours.

Is something off, or does it really take an entire day to copy one moive?

It depends a lot on the specifications of your computer and whether you are compressing to BD25.

I could increase the memory to 8 GB. Would that help?
I only run DVDFab without any other programs running or surfing the net.

Why does it take so long to copy a movie? I'm trying to copy X-Men: First Class, and it takes about 5 hrs?
