I just installed precise and decided to see how easy it would be to playback a blu-ray disc. I was actually surprised by just how easy it was. All I had to do was
1) install VLC
2) download the KEYDB.cfg file from http://vlc-bluray.whoknowsmy.name/
3) place the KEYDB.cfg file in ~/.config/aacs/
4) load the blu-ray in vlc, making sure to chech the no menue checkbox as VLC will most likely choke on menues
5) enjoy your blu-ray (unless it is protected by bd+).
This worked great on my computer. The only downside is that this only works with discs that only use aacs encryption. Any disc with BD+ will choke, and here comes my question. Is there anyway of watching a BD+ encrypted disc using VLC without having to rip the movie first? Is there a libbdplus library being worked on?
For those watching blu-rays in vlc, bear in mind that you need to update the KEYDB.cfg file on a regular basis for it to be compatible with your newest discs. The current KEYDB.cfg file is only about a week old, so the site seems to be up to date. I tested it on two of my discs (2001 and total recall) and both worked well.
