If you have a Samsung TV, try to stream a blu-ray m2ts to the tv.
First: The samsung tv does not recognize the audio ids, these ids are not the same as the usual ones in streaming. This results in no Audio on the TV.
Second: Try this same m2ts remuxed in a TS. In this case, the tv plays the video too fast if the framerate is 23.976. Changing framerate to 25 or 30 (Normal PAL and NTSC frame rates), now the video is well played.
I don't know if it's due to bad profiles or if the does not simply support this kind of streams.
I'm just surprised that 23.976 MKVs play just fine.
If you need ts and m2ts samples i can provide you samples. You can generate samples yourself with

If you don't know it, this tool help you in remuxing mkv to TS/M2TS. You can change frameRate and disable new bluray PES in on of the configuration options.
