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.)

WetGeek From an ebook I am currently reading:

Audio CDs consist of a sequence of music tracks in a digital format called CDDA-WAV. They were designed to be played by very simple consumer-electronics devices a few years before general-purpose computers developed enough raw speed and sound capability to decode them on the fly. Because of this, there is no provision in the format for even simple metainformation such as the album and track titles. But modern computer-hosted CD players want this information so the user can assemble and edit play lists.

Enter the Internet. There are (at least two) repositories that provide a mapping between a hash code computed from the track-length table on a CD and artist/album-title/track-title records. The original was cddb.org, but another site called freedb.org which is probably now more complete and widely used. Both sites rely on their users for the enormous task of keeping the database current as new CDs come out; freedb.org arose from a developer revolt after CDDB elected to take all that user-contributed information proprietary.

      Jumpy The original was cddb.org,

      Interesting. After my original toe-in-the-water, I found out about the Asunder utility. It will extract all the info from a CD, or as little as you need, and automatically uses CDDB to locate the album and track information. It will optionally create a playlist as it extracts. It offers a broad choice of encoding, works smoothly, and quickly, and doesn't require any effort from the user. And it's in our repository.

          WetGeek I've always used asunder. If you want to include CD/album covers for your rips, or need to modify the tags, easytag is a joy to use.

          One other thing about asunder...one of the things that I really like about the program is being able to rip to multiple formats at the same time. I like to rip to flac for archival purposes and mp3 for everyday use.
