It may explain then why the files as ST-DL also sometimes don't work?
Here's a topic on it but no answer from Mike atm: viewtopic.php?f=12&t=26034
no that is another issue I think because I have the original spears and munsil m2ts and ST-DL wont work even on the x700. Using yusesoap tool, no mkv involved.
ok after a bit more tests. The DT-DL TS files that wont play are the ones made from an MKV (mkvtoolnix) that has both layers in two different tracks( not merged into P7 ST, the early remux on rarbg )...
But if your source is an untouched bluray folders or a ST-DL P7 MKV made with makemkv or yusesope tool, it can be demuxed and remuxed into a working DT-DL TS.
EDIT:. if I remux the dual-track mkv to ISO first and then to DT-DL TS, it works.
So far so good. I watched 5 DV movies (FEL P7 and MEL P8) already with the 5ghz wifi and not a single issue. FF/RW on the wifi is as fast as my x700 USB. My router is only 15 feet away from my player.
No dual-track green/purple screen and no long movie FF/RW bug is so great!!
No DD+ support (except atmos) is not a big problem, I just use my C8 internal plex app. Same for cropped content.
Also, I FF to the ending credit of Power Rangers just to make sure FEL stays in sync (Chromecast loses FEL sync when you FF) and no issue there, Bright white text without any ghosting.
I also like the fact that the x800m2 is pickier than the x700 about what works (or not) because I noticed that when a DV file is broken, the x700 will still play it in DV but the RPU doesn't work at all(fel still works tho).
The x800m2 will just refuse to play the broken DV file. I much prefer this behavior and I fear I may have watched fake DV on the x700 with some particular files.
Does anyone have an idea why I get different results in the DV enabled ST-DL video track when I follow these workflows:
Source: Ghostbusters Afterlife [MEL]
a)
- Use MakeMKV directly on the blu-ray
vs:
b)
- First mux the blu-ray to TS with TSMuxer
- Then mux the TS to blu-ray with TSMuxer
- Use MakeMKV on the blu-ray created by TSMuxer
for the same movie,
in the first case I have a 49.3mb/s 42.7gb video track
in the seco case I have a 48.0mb/s 41.6gb video track
I know workflow b) seems odd at first sight, but I wish I could store just the TS, and then get the (correct) MKV at any time when I need it.
Now instead I need to keep the blu-ray arround, convert to TS to watch on X800M2, and convert to MKV for other purposes.

I don't know about your question but in the case of a MEL movie like Ghostbusters , the best way is to convert profile 8 and your TS will work everywhere.
so p8 for mel and p7 for fel, that's what I do.

That's weird indeed. Maybe waste of space in MEL that tsMuxer would solve when muxing? I recently had a title with 1.6 GB MEL, of which RPU was 36MB. You can of course investigate by demuxing BL and EL from both mkvs and compare sizes.
Even better of course is what RESET_9999 suggested and convert to Profile 8.1 "BL+RPU". You'll have no EL at all.
I had a chance to play with my X800M2 today and my experience wasn't quite as good, but I've still got more investigating to do.
Every M2TS I tried to play worked fine to start with, with DV recognized and sent correctly to the TV. Unfortunately most of the files failed at some point during playback: either they just stopped playing (and the player went on to the next file in the folder), or more concerningly they locked up the player and it had to be power cycled. Sometimes it happened within 30 seconds, and sometimes the movie played fine for ~10 minutes before failing. The failure always seemed to happen at the same point in the title, so it looks like there's something in my files that the player doesn't like.
Now I'm not devastated, because all my M2TS files were converted from MKV, and so those files have been through a bunch of different tools at various points in their lives, and it seems very plausible that some bug in some version of any one of tools could have broken the strict conformance that a UHDBD player needs.
So my next step is going to be to try re-ripping straight from a full disc backup with tsMuxer and hopefully that will give the same good results that @RESET_9999 is having. I'll report back whatever happens (might be next weekend at this point).
Some other observations about the X800M2:
I had the FEL_test_for_AVS.mp4 file handy so I tried that on a whim and it surprised me by playing fine with RPU and FEL both visibly working. Obviously that's not a full movie so I don't know if it MP4 FEL playback would be completely reliable, and I didn't investigate which audio formats would be supported.
The quality of the player seems pretty good. I like the remote and the setup menus are mostly clear and comprehensive. The on-screen playback info display is extremely useful with the way it shows the source video and audio formats and current bitrates, and what formats the player is outputting. I'd give the interface responsiveness of the player a B- grade. It's a lot better than the Zidoo z9x, but not in the same league as Apple TV or LG TVs. The interface is rendered in a crappy resolution (maybe even less than 1080p?) and upscaled, which made me think the player wasn't outputting 4K at first.
I thought I might be able to get away with using the 100Mbps Ethernet, but got stuttering very quickly in the second file I tried (Back to the Future Part II, which works well for testing that because it has very high bitrate scenes in the first couple of minutes). I switched to Wi-Fi, though, and that does seem to be working well. It's connecting at ~300 Mbps to my access point about 6m away.
My favorite feature of the player so far is the Bluetooth audio support, which seems to work fantastically. The player has the neat capability of outputting audio over HDMI and Bluetooth simultaneously, which is great for verifying that lipsync is correct, and it seemed perfect in my testing. The quality sounded superb on my WH-1000XM2 headphones, presumably because they and the player both support Sony's high bitrate LDAC codec. I did all my tests with Bluetooth audio disabled too, just in case that was the cause, and it didn't seem to make any difference: everything that failed with Bluetooth audio on also failed with it off.
Encoding DTS-HD takes in a lossless LPCM stream, encodes a lossy DTS core, and saves the rest of the discarded audio as lossless extensions. When decoding, the extensions are recombined with the lossy DTS core and decoded to arrive at the original lossless stream.
[...]
A TrueHD+AC3 track has audio frames alternating between TrueHD and AC3. It's just two completely separate streams interleaved into a single track, kind of how STDL puts two distinct video streams into separate NALUs of a single track.
Thank you for the superb explanation. I guess I had a vague memory about how DTS-HD works and assumed that TrueHD worked the same way.
I didn't investigate which audio formats would be supported.
only dd+ without a core doesn't work. And strangely DD+ Atmos (without a core too) works.
and yep ripping from a disc is the way to go, thankfully 95% of my movie library was done from untouched bluray folders
did you convert to DT-DL ?

I checked a movie. Power Rangers ending credit is bright white in FEL and dark grey in MEL/HDR10
I had a chance to play with my X800M2 today and my experience wasn't quite as good, but I've still got more investigating to do.
I'm having a similar experience, may just be my wifi and or my DLNA messing up at times.
Also I can't seem to CEC control the player with my LG remote.. only the menus.
I'm going to compare with an M9203 oppo clone (1gbps lan etc).
