As such, mkv just carries the same one subtitle (for each language of course) that's in the AVC mainstream of a 3D disc. Regarding video, main difference between 3D bluray and 3Dmvc-mkv is that the AVC-stream and MVC-stream are interleaved into one elememtary videostream. This is what MakeMKV does.
Are you sure that all 3D versions of Avatar do this? Mine shows only 1 PGS subtitle and it's assigned to a 3D plane from the MVC. What tool should I use to see the 2nd subtitle track? (if it's there)
