Make MKV "failed to open disc" on a new movie, which was annoying, but it suggested that maybe there was a new form of encryption. So I skipped that and went back to ripping my extended LOTR Blu Rays. Make MKV had done a fine job on FOTR, but gave me the same failure message for TTT. Huh? It's now failed to open every disc I've tried out of the last 5. Anyone else having the same trouble?
