No Sound on any Profile for Panasonic 65VT50

[tkpro]

I have a issue that I hope is a simple solution

I have Mezzmo 2.6.7.0 and have been streaming to 3 Samsung Tvs ( D610 and 2 D550 ) everything works pretty good. Just purchased a Panasonic 65VT50 which is their flagship TV hoping that it would fit right in my mix. Wrong !!!!! It seems my TV wont play any of my mkvs without transcoding ( All the Sammys do ) says No Audio on Panny when trying to play from Mezzmo. Its seems only mkvs with Dolby track play, anything else says No audio on Panny. ( I have tried all availible profiles ) I have LG bluRay player and if I try to play Mezzmo through LG everything plays. No trancoding , as I said their flagship TV, well some might say just use your LG Well Im a little bummed out if that is my only solution. Why can't this TV play mkv with DTS or is it just a profile adjustment I hope so as I only see 2011
Panasonic Viera DTS no 2012 if that makes a difference.

Does anyone else that owns this TV have any ideas? It would be a long process to pre transcode all my mkvs that I would really like to avoid
I am not running through any avr ( would that make a difference )

Please help
