Basically what the title says. I'm using MultiAVCHD. The resulting BD folder has a correct m2ts, with the extra audio and sub, but PowerDVD do not show them. Also, the playlist info (or mpl, I don't remember exactly what files are edited) is correct, I have checked it with BDEdit.

I have also tried to edit manually with BDEdit and add the streams manually with TSMuxer.

Am I missing some step? Maybe my BD has something weird?

I can upload the FULLBD if someone wants to check it.
