Did you still get lossless DTS HD Audio from the new MKV?
As Jatin mentioned, the mkv sometimes creates a problem.
I have 8 GB MKV rip (dont rememeber audip format but its HD for sure, video is full HD 1080p), of Stomp Live! but when i play it on my PlayON HD, video doesn't stutter, but I am not able to skip the filed more than 1.5x times the speed.
However, I have 30GB BRRips in M2TS format with HD Audio and my POHD doest fight hard to play the movies.. I mean sometimes it plays them smoothly, although pause and play are delayed. Sometimes the player hangs, and its just not able to play the movie...
This is with the same movie itself... I wonder if the problem is with the HD. The HDD is in the internal SLOT of the POHD itself...
Any light here?
