No it does not support Dolby Vision and it’s doubtful it will in the future (from previous forum posts). Single layer Dolby Vision… which is what the demo files are made with can be played back on a few media players however movies that are released via Blu-Ray use dual layer which Can’t currently be played back on anything other than the expensive Oppo media players.
No. It’s a technical implementation. Dual layer means you have one track with the regular video stream and the second track contains only the Dolby vision video data. Single layer just merges it all together.
I assume the difference is that for a streamed movie, the client can tell the server whether or not it can handle Dolby vision media files and the server then streams the appropriate format.
On a disk, a player that does not support Dolby vision can play back the movie on the first track, but a DV player can also read the 2nd track to improve the video … so it is a way of making a disk backwards compatible with non DV players.
Whomever ripped it didn’t remux it into a single layer file. Remux doesn’t guarantee single layer. You’ll have to look at the mediainfo. If you have dvdlab for Windows you could probable do the merge yourself.
