Hi, new here but I have played a lot with my AppleTV and @yusesope instructions to get the best video/audio on my 4k backups.
So far, I can get a single layer DV + LPCM 7.1 (converted from TrueHD/Atmos) using the same command as above.
I believe I know the answer, but am I right to believe that in this way we lose Atmos? I have learned that AppleTV doesn't allow to play Atmos anyway, but I was wondering if Atmos is lost in the conversion anyway.
I have a 5.1.4 speaker setup and I'm finding myself conflicted on the following:
1) Watch the backup with DV + LPCM 7.1 (converted from TrueHD)
2) Watch the backup with DV + DTS-MA (I believe this should work with MP4 but I haven't tested it. Or is it worth more to convert DTS-MA to LPCM instead of TrueHD, again if possible?)
3) Watch the backup without DV but with Atmos (is there any appreciable difference with HDR10? I have a LG C8)

Are you talking about Sony UBP-X700B?
I didn't even knew there was a device capable of playing Dual Layer remuxes and lossless passtrought!
And it's also not very expensive!
The Ethernet thing is a bummer but where I would place it sits next to the wifi receiver.
Can you confirm this device plays everything?
I'm interested in that topic too, I'm currently testing Dvdfab ripper to have the single layer DV, but if the Sony UBP-X700B works with dual layers and lossless passthrough that could be definitely a solution (and maybe cheaper than a software solution in the long run). I would use a USB SSD drive for that.
Thanks in advance!
I can make some comments regarding Sony x700, but you have to take everything I say with a heavy dose of caveat:
1. I haven't been paying attention to 4K HT hardware for almost a year, to just enjoy what I have, so I have no clue what's now out there, what's available that might be a better option.
2. I didn't buy the x700 to solve a specific problem, but found out what I already had can do things, while having its own unique quirks and features. It's a very Jerry-rigging approach of things.
it certainly does NOT play EVERYTHING. According to REST_9999 it handles most DV MP4 remux of TrueHD/Atmos track very well, from my limited exeprience with DV+DTS-HDMA remuxes, not that great. Like we've mentioned earlier, when fast forwarding a MP4 DV remux, the x700 will hard crash forcing you to unplug its power to hard reboot. It's definitely an unofficial capability that "just happens to work, to a certain degree". But it's hard to pin point culprit in a chain of blame: player hardware? software update? UHD ripper drive hardware? software update? demux/remuxing programs, version updates, specific line of commands? nobody knows! Like I said, very Jerry-rigging approach: patch up a bunch of things from existing tools, and it does something! magical! why does it work (or not) or how to improve it? meh...
There's no way to preserve object-based metadata (atmos/dts-x) in lpcm for your appropriate AV receiver to unfold back to specific atmos/dts-x channels, except to take what's there in the converted lpcm track and use algorithm to up-mix certain audio effects into ceiling channels, "up-mix", but not the same. I'm not content with losing atmos, which is why I only backup DV+DTS-HDMA titles and don't touch DV+Atmos titles.
I have no experience with dvdfab but the yusesope methods.
I do not know the specific wifi capability of X700, it streams netflix 4k HDR content fine, but those are only around 20-30mbps bitrate. Consider how Sony priced X700, to skimp on built quality and features (no gigabit ethernet), I doubt it's equipped with the fastest wifi card to handle 100mbps+ bandwidth. But "does it, or does it not?" IDK.
