btw the audio does have a second track i can use that does not transcode,its just in general major buffer issues with MKV files and not MP4 files 
anything i can do about that? chromecast ultra,appleTV etc etc. idk how i would be able to convert a 4KUHD hdr mkv to mp4
The container does not matter. As you noted in your original post, it is transcoding that causes buffering. Choose the AC3 audio, not TrueHD audio, and the video will direct play.
Using another client - Chromecast, AppleTV, FireTV, etc - will not help. TrueHD audio will still transcode because the TV does not support TrueHD audio (and neither the AppleTV nor FireTV can bitstream TrueHD; not sure about Chromecast).
As I mentioned in an earlier post, if you want to play TrueHD audio without transcoding, you need an Nvidia Shield and a receiver that supports TrueHD audio. The same for TrueHD + Atmos, dts-HD MA, & dts:X.
If you wish to remux from mkv to mp4, consider XMedia Recode. Choose to copy, not convert the individual tracks. I’ve never used XMedia Recode with 4K HDR video. It works fine with AVC 1080p video.
Note that the mp4 container is limited compared to mkv. TrueHD and dts-HD audio are not supported. Neither are PGS subtitles.
I did a exact copy to MP4 and i still remained to keep the HDR,however i still had a buffer issue idk wether that was maybe my end or not…
Yeah, a lot of TVs still have 10/100 Ethernet (including my LG B7 OLED). It would probably cost an extra $0.50 to make it gigabit. Oh well…
Glad you have things working.
So far yah ^^’ a mate of mine had the same problem until he used his wifi… is their a way to test this actually only thing i can find is that its a RJ45 port
I did not see anything in the docs about the port speed. Mine is plugged into a gigabit switch, and the switch reports the port speed as 100 Mbps. Others on AVS Forum & similar sites also report 100 Mbps for their TVs.
its just downwords sad…you spend hundreds some even thousands on these things…and you get a bad port.
