If you want to make something playable by almost any hardware that does
H.264 acceleration, you should limit yourself to BluRay profile which is
H.264 High Profile/Level 4.1. The Taj scene is High Profile/Level 4.2
which is why there are problems.

You will have to lose the full 1080p50 though  - level 4.1 only allows
1080p24.

MediaInfo is a good help here.
