I am trying to liberate my old DVD collection from its optical media prison. I bought a cheapo external DVD drive, but I can't get the DVDs to play or even cooperate for ripping. I can open the disc in the file manager and see the files on it, but I can't play anything. Do some searching, I see a lot of things about installing libdvdcss, libdvdread, and libdvdnav. I did all that and still nothing. VLC gives me an immediate error. I also see a lot of stuff about installing and using regionset to change the region setting on the drive. However, that package seems to no longer be available. Any ideas of what else I could try?
