In addition to the warnings, the new README will include suggestions on how to trim back subtitle tracks for disc-based formats, based on number of speakers, language overlap, and quality of translations. This is sure to offend someone, particularly those very kind and generous people who helped us have first-rate Icelandic subtitles, only to see them left off the disc. You don't have to follow these guidelines, of course, but if you do, you can blame me when people complain ;)

Sorry again, I was led astray by the fact that tsMuxerGUI allows you to create non-compliant discs, software players didn't mind playing them, and the Blu-ray spec itself is so readily available*.
