Once you buy the blu-rays, there's no need to rip them. You can just download them, as you already have a license.

Come to think of it, you can skip the first step too, and just download them.

Depends on the content, but some disc rips, some ytdl, some internal corporate stuff that I just hit Save As. The nice thing about the Quest, it is pretty much just a computer so lots of formats can get played (and you can even just copy files to the filesystem in a format the e.g. BigscreenVR or other video player apps can read)
