I just found out the ugoos am6b+ is no longer sold anywhere in my country. Now I dread the day mine dies.
Still no other devices that are capable of the same things as this box?

I have been using my Sony X700 to play DV content. Annoyingly my TV (Panasonic GZ950) doesn't support TV led DV, as I was led to believe when I made the purchase.

@RESET_9999 or anyone else knowledgable, are there any viewing benefits to replacing my X700 with a Ugoos AMB6+ when my TV only supports player led DV from external sources?

When is the encoding date? I believe Framestor used an older version of MakeMKV and/or MediaInfo for a while, which didn't inclue the DV flag, or something along those lines. What does a modern version of MediaInfo say?

So us AM6b+ owners are now in a situation where we are blessed with 3 different current builds/paths:

"OG" cpm on A15-HEVC, seemingly focusing on only full bitrate remux/lossless audio. https://github.com/cpm-code/xbmc/releases

avdvplus, currently on release 5 (which is what I am running right now), focusing on everything within reason and DV improvements in general. https://github.com/avdvplus/Builds/releases

U3k on B11, similar to avdvplus, but also backporting stuff from Kodi 22 (mostly GUI rendering stuff if i read it correctly?), maybe halted/discontinued as the repo is archived. https://github.com/CE-Repo/xbmc/releases/tag/B11

My only issues, which persist across all 3 versions are random crashes, completely taking down the AM6b+ , and some DV content completely blanking the screen (on a scene by scene basis) on my LG E6. (Latest content is Slow Horses S05 and Fallout S02 P5 versions, in which every episode has issues sooner or later), which can be fixed by removing CM4.0 using dovi_scripts, which are fine, but not super nice, as this can happen at any point in a movie/show, such as 30 minutes into a movie, which is not really when one would want to start running scripts on a file.

Just wondering if there is a preference / comparison, as i have lost the thread by now :P

CPM and Jamal (u3k) have both retired and are no longer working on this project. At this point, avdvplus is the only build that should be used.
If you haven't already, you should open a ticket regarding these crashes. The issue is likely easy to fix, it's probably related to the fact that you have a first gen oled tv.

But it does show DV in the HDR format line, right?

Regardless, the P5 versions are always better than the P8 versions, HDR-wise.

At least according to this.

But it does show DV in the HDR format line, right?

Regardless, the P5 versions are always better than the P8 versions, HDR-wise.

At least according to this.
Yes still in the format line besides that little bit missing

Looking at that link, I feel like a P8 UHD Remux would still be slightly better than a p5 (unless Movies Anywhere or BCORE) due to higher bitrate. I think a P8 Movies Anywhere is somewhere between a P8 UHD Remux and a P8 UHD Encode/Hybrid Encode. (Haven't seen a lot of p5 MA releases so haven't given them much thought)

Purely in terms of HDR, I believe a P5 will always be better than any P8, BD remux or VoD WEB-DL. Purely because they (P5) retain more dynamic range than P8 due to their more efficient colour space.

Except when it comes to ATVP/iT content, apparently the colours in Apple-sourced content looks distorted, something to do with the static colour reshaping metadata.

thats apple stupid static color reshaping. All their DV contents have this difference: red always looks brighter/orangish. sometimes it's less apparent.
this static metadata is removed when you convert the rpu to P8. Apple has no respect to the creator's intent, I did a video about it on my youtube channel.
Never watch iTunes P5 web-dl if you care about accuracy, always convert it to P8.
I'm not quite sure what exactly causes this or what the difference looks like as I haven't really looked into it as I try to avoid Apple-sources content for said reason.

Perhaps reset could can comment in little more detail on this?

mostly noticeable with orangish-looking reds.

@RESET_9999 given this:

Since L2 trims are not static, what is the best practice here: generating new metadata or keeping retail RPU?
