I've mentioned MakeMKV as the tool I use to back up my Blue ray discs. Since registering less than a month ago there have been 2 updates, indicating development is still pretty active. The latest release (as of this writing) is 1.9.7.
Around 3 months ago I posted a video on Youtube describing how to create MKV files from televisions shows on DVD using Handbrake. Today I found myself using the same principle to save myself many gigabytes of space encoding 26 DVD dumps. At some point while I was experimenting with different programs I started dumping the entire contents of DVDs to the 2TB hard drive in our KODI/XBMC system. Most of the DVDs I dumped were dual-layer, so some were over 4GB/DVD.
MakeMKV converts video from proprietary (and usually encrypted) disc into a set of MKV files, preserving most information but not changing it in any way. It can store multiple video/audio tracks with all meta-information and preserve chapters. It also can instantly stream decrypted video without intermediate conversion to wide range of players, so you may watch Blu-ray and DVD discs with your favorite player on your favorite OS or on your favorite device.
A couple of youtubers, demeted12 and Richard Pinka, commented that I should do a video on how to "install" .tar.gz and/or tar.bz2 files. Files that end in .tar.gz or .tar.bz2 are files that have been compressed together into a single file.
I've been using XBMC, now KODI, for a few years now. Over those years I've tried ripping my optical media using a wide variety of programs, exported to many different formats (OGG, AVI, MP4, MKV), and used a few different naming conventions (with underscores, without underscores, appending DVD/Blueray to the name, with(out) date). The different naming conventions really stuck out last night while I was adding more video to our KODI server.
