Unfortunately, I am also experiencing the green DV issue, so I’ll just keep waiting and hope that this will be fixed soon.

there's been no fix put in yet that I know of. you were only told that testlfight was the best place to see announcements of chnages.

Ah, fair enough.

Any updates?

I've seen a few reports that seem to clarify quite what DVDFab seems to be doing.

AIUI it is taking a Dual Layer - BL (base layer core YCbCr HDR10 hevc video), EL (Dolby Vision enhancement layer hevc video which extends 10-bit to 12-bit?) and RPU (Dolby Vision metadata stream) and processing it as follows.

It discards the Enhancement layer (which on some discs contains almost nothing, but on other discs has a significant amount of data), and instead muxes the YCbCr HDR10 hevc base layer with the Dolby Vision RPU metadata (that is the dynamic metadata that HDR10 doesn't have that allows a Dolby Vision display to optimise and improve display over static HDR10 content).

So when you rip from a UHD BD DV disc to a DV MP4 in DVD Fab you are losing the benefit of the enhancement layer (which can increase the bit depth?) but retain the benefit of dynamic metadata? (It seems the use and benefit of an enhancement layer depends on how the original content was mastered. In some cases it may mean there is next to no difference in the two versions, whereas for others there may be a much greater difference. It may also depend on what your display is capable of?)

This single layer video stream may well also be non-standard and not an approved single-layer format as defined by Dolby. (i.e. using YCbCr HDR10 as the video stream may not be what Dolby want you to do for a single stream file that doesn't need backwards compatibility in the way a DV UHD BD does)

I may also be very wrong... And the situation may be different to when @wesk05 originally posted that analysis (where it seemed to suggest that the RPU stream was fixed and just used to trigger a DV mode change on the TV, and this static RPU data may explain the difference observed between DVD Fab SL and HDR10 mode display)

Will this improve and fix DV Problems in MrMC?

Not necessarily, we have very little in common with Kodi now days.

@davilla might have more info on timeline and what to expect.

some news?

I really would love a fix for dolby vision since a lot of my media is now DV
