I'm using a Sony x700 with an OLED TV and so far, only the file with 7.1 lpcm works. When I make a DV mp4 with DTS-X, DTS-HD or even DTS, it plays in DV without sound. It doesn't even say '' audio not supported'', just like there isn't any audio in the file.
btw, I watched two complete movies in Dual layer with lossless 7.1 lpcm without any issue. this is really awesome.
