I've run into a problem with The Lord of the Rings 2 - Extended version (Part 2) BD, that I think might be a bug. I'm creating an uncompressed ISO of just the Main feature with two subtitle tracks (originally sub #1 & sub #16). I set the second (#16) subtitle to be the default but, when played, the result ISO is set with sub #1 as default. So far, have not experienced this problem with any other discs. Logs attached if someone is able to help.
