Bluray playback tip: mount first!

[Jason_25]

I just tried playing a bluray disc for the first time in a while and forgot that it needed to be mounted first. I was getting these cryptic index_parse errors with no other explanation. Only 1 hour of troubleshooting time lost this time. It could have easily been something that I had to replace the entire computer for or troubleshooted for weeks, months, or years. What a relief.
