yes the new 7.1 EC3 audio encoder does that and you can ignore it. see:
viewtopic.php?p=127616#p127616
Beware that the new version of the script auto-mux to TS. And it will also keep the lossless audio as track #1 so dont forget to switch to the audio track #2 on plex or the native lg player otherwise you"ll get HDR10 because plex will have to convert the audio on the fly and plex apparently cant do it without breaking DV. I hope one day, PLEX will add DV support for when it does "direct stream" instead of "direct play". This way, we wouldn't have to convert lossless audio to EC3 7.1 since plex can do it on the fly.
If you don't like the new auto-muxing behavior, it can be turned off by editing the bat file.

Have a quick question I haven't been able to find a good answer to. I have ripped my Dolby Vision discs to my NAS. To watch them, I'm currently just using plex on a shield. But the red push issue is annoying, and no FEL support. Also, I have an atmos system
It sounds like either an Oppo clone or an X800m2 is the way to go. Is one better than the other? Also, what is the reason everyone uses the Sony instead of the Panasonic UB820? Is it not able to play files from wifi/usb?
Thanks

I would like to generate DV metadata, with DaVinci Resolve, for files I've already used madVR on. Is it necessary to remove DV from the files before creating a prores (MOV) file?

Check out the signature in the post above yours. Look at the "DoVi Playback Devices" tab.

Thanks Gatorman, that spreadsheet is why I figured the sony x800m2 was the way to go. But there is no mention of UB820, and it's been difficult to find much discussion about it. Is this just because it's more expensive so fewer people bother to go that route, or is there something negative to it and it should be avoided?

No
Resolve will discard.

actually, it's the dovi_tool that will discard the old rpu when you'll inject the new one. The RPU gets removed when you convert to prores so Resolve wont even know the original had metadata(it wouldnt matter if it had metadata anyway).

From what i can read about the UB820, it has poor file playback compatibility.

I've used EAE to encode 5.1 audio tracks (DTS XLL to EC3). Is there a way to set the bit rate?

Has anyone had to enter an active area offset for a film in which the aspect ratio changes scene to scene? I saw that there was some discussion about IMAX films earlier in the thread, but this wasn't covered.
Is it possible?
Tangentially related, if I am playing all my files back using TS files and an Oppo, is the active area even respected/used? Sorry if this has been asked/answered before. The thread has gotten quite long.

From what I understand, if you are using the original RPU there is no reason to edit the active area. If you are using madVR to generate DV metadata, it will not make a difference. If you are using Resolve, you have to edit the blanking for each scene to match the active area. RESET_9999 has a YouTube video showing this very thing.

That's interesting. As a test, I extracted the raw RPU and reviewed it. I don't see any offset areas set in the Profile 5, untouched RPU. So, I wasn't sure.
As another test, I didn't set an offset area and it looks like everything played fine on the Oppo. It seems to ignore the offset area. But it would be good to have that confirmed.

dont use EAE when the input is 5.1 or 2.0. Use 6-3-4 and you will have the option to set the bitrate and the encoding will be much faster. ( you can also batch encode up to 13 files with this workflow)
in the next version, I'll add the option to use ffmpeg when 5.1/2.0 input is detected for EAE (6-3-5). This is already the behavior for all the other DDP workflows (mode.I mode.f mode.h ).

Yes, so far, all the HDMI devices ignore L5 active area so it doesnt matter to them and the letterbox will appears raised if the content is lifted above 0.025 while devices that use L5 will be fine(TVs internal players)
"Avoid using positive values over 0.025 on the LIFT trim control for letterboxed content. (Negative Lift values are acceptable on all versions). The
current implementation on Ultra HD Blu-ray devices apply the Trims to the entire image area, including the letterbox blanking area, to allow subtitles to
appear over them. If the scene contains positive Lift values over 0.025, this may cause the letterboxed area to have elevated black levels during playback.
An alternate way to achieve the desired result is to use a combination of GAIN and GAMMA trims more aggressively as these controls are
manipulating the tone curve to achieve a more lifted black effect without using Lift. You can also choose to go back and modify your original HDR
content to lift the blacks slightly and then re-analyze and trim without the need to have a positive value on the Lift trim over 0.025. If the active image
area matches the canvas aspect ratio, (i.e. there is no letterbox), positive Lift can be used."
"Dolby Vision, by design, has metadata (L0/L5) that describes the active image area and the portion of the image that has a letterbox (or blanking).
Dolby Vision mapping algorithms (and subsequently playback devices) are designed to apply mapping only in the active image area.
This works well for many devices but on HDMI-based devices like set-top boxes and Blu-ray players, this metadata is ignored as the
letterbox or blanking areas of the image are used to present subtitles and other graphics to the end user. Due to this implementation
on these devices, any positive lift applied to Dolby Vision content during the “trim pass,” will raise the black levels in the
letterbox/blanking areas of the image and can become distracting to the end user. Dolby recommends a maximum positive lift
value of 0.025 while doing the trims on letterboxed content during the Dolby Vision content creation process"
