Will do. Supposedly it's pretty easy to install makemkv and compile the codecs from that to allow VLC to play them, I just need time to play around with that.

I tried a few different codec installations with no luck, gonna try this one next. I guess you also have to set VLC to emulate whatever region the disc is locked to as well but I forgot that step, so what I already have done might actually work.
