I like it pretty simple.
That's why I scrapped MakeMKV altogether as soon as I had tested it, well, I should say: As soon as I got it installed.
That took ages and is a very complex procedure. (I had inquired about how to rip DVDs in this forum.)
I use K3b also, for CDs first of all, and after someone pointed me to it also for DVDs:
They are ripped and saved as an "iso" but you can play that iso file as if it were the DVD - from your hard drive.
Fab!
With Blu Rays I have no experience but then I don't have no Blue Rays and no BR player either, so no need for that format.
(For copying CDs I use Brasero, plain and simple.)
