Using Clown BD and converting some ISOs into M2TS, I noticed Se7en's DTS-HD MA being listed as "7.1 (strange setup)." Googling that gets me to, among other places, Doom9's eac3to forum/thread and something about "strange setups" not mapping correctly. I haven't watched the movie for a while, maybe never from the 7.1 Blu-ray, so I have no experience with incorrect mappings.
Anybody know anything about this? Perhaps I did something wrong when I originally ripped the BD and I should go back and redo it?
