The 3D Blu-Ray spec says:

> P.9.3.3.6 Offset metadata
> The offset_metadata() shall be stored in the user data container

I'm not a big expert on these things, but doesn't that mean it's part
of the MVC video bitstream? In that case there's probably no need to
store it in separate MKV fields/properties?

Best regards, Mathias.
