Dolby Vision not working on 7.24 with single layer mp4 files

@RosaVanWinkle @DaMacFunkin

Please read my feature request post.

Importantly:
1. DVDFab’s so-called single-layer DV seems to be not real DV… so be careful when being satisfied with it :wink:
2. Yes. I would agree that the problem may be more Nvidia sided. However, as I also pointed out: the Exoplayer could play it and then Plex would not rely on the Shield’s internal player what could be the key… and that’s why Plex is able to play dual-layer DV on some TVs. It uses another player
3. Even if not, it could also be a licensing issue… and then Plex or Nvidia would have to found out how to implement it. (I cannot imagine that there is a built in hardware limitation on the Shield… especially external software like Plex what comes along with such a license should be able to play dual-layer DV even if the Shield itself doesn’t).
