Thank you, now I can confirm it. The mistake I did (for quite some time now and I regret not having understood it before ) was to play the m2ts inside the BDMV folder without using the AVCHD virtual folder procedure. I did that to save the hassle of putting back every time the BDMV folder of each ripped disk at the USB root of the X700, at the cost of losing chapter selection and forced subtitles. I thought that since the DV flags were applied to the m2ts of the BDMV folder I created with tsmuxer, it was safe to start playing the muxed file navigating to the STREAM folder and simply playing the m2ts from there. Instead, if one wishes to do that, the output of tsmuxer must be uniquely a ts or m2ts file. The BDMV folder outputs DV content only when played with the AVCHD method, otherwise it will keep playing base HDR10 content without the enhancement layer.You just have to remux the original m2ts to a new m2ts(or ts) with tsmuxer to get DV. Your new m2ts will have the proper flag
That is the strange thing. I had plans to buy a Denon AVR for enjoying Atmos content, and I thought I could confirm that the Atmos track within the BDMV folder I created was a THD+AC3 core. The LG CX supposedly supports Atmos decoding, although naturally there is no real benefit in using the TV internal speakers. Several times I played MEL movies (Profile 8.1) using the poor internal TV player and the TV indeed showed the Atmos label whenever the given file had a TrueHD track. But it seems that DV FEL contents with Atmos track will make the label appear only when they are in the form of .ts file, even if the x700 actually shows that the track played is TrueHD. So I think that the BDMV folders I created are correctly muxed and this is just a visual bug of the LG CX. When I will purchase an AVR I hope the content I have created in the past will be fully compatible.I don't have a CX to know how audio is treated, but you're expecting the CX to pass the TrueHD audio through to an audio device via eARC? What does the device say it's decoding? My understanding is that the CX does not have a TrueHD decoder to play back the audio on the TV. The Atmos support is limited to an EAC3 decoder. Supported codecs: AC4, AC3 (Dolby Digital), EAC3, HE-AAC, AAC, MP2, MP3, PCM, WMA, apt-X (refer to manual)
I wonder, in your case the TV too shows that is receiving Atmos content? That info would be really helpful, thank you very much.I send my video+audio from the X700 through an AVR to a TV, and the AVR plays and decodes and shows the info for TrueHD Atmos when the audio stream is properly muxed with an AC3 core.
