I know there's this one on Rentry: https://rentry.org/bingremuxin but besides that there's basically nothing. That rentry guide is okay but it doesn't cover a lot of stuff, like DV or DVDs.
The easiest tool is MakeMKV. But you'll often encounter opportunities for efficiency (eg stereo DTSHD to FLAC) as well as requirements to convert* for hardware compatibility. That's where ffmpeg and MKVToolNix are good secondary tools for customizing the remux contents.
*Not transcoding. Rather, lossless formet 1 -> lossless format 2.
Converting from one lossless to another is still transcoding as you are changing the encoding format of the data. The conversion being lossy or not is related to the choice of formats, not the process itself.
