Lip sync problems using Samsung

I have a Samsung TV - 60F5500AF plasma, A Samsung BR - BD-F5900 and I am using serviio 1.4.1.2. The sound is not in sync on some files. - .mkv mainly. I can send logs - please tell me which ones and where?
thanks, Scott

Does anyone have a suggestion as to what to try for my issue? I have a variable problem, sometime not at all and some times quite a bit off on the sound. I have removed all processing on the TV to try to eliminate the problem but that didn't work. Any help is appreciated
Thanks

Does anyone know of a another media server software i can use? I cannot get my questions answered or issue resolved here.

The files are not transcoded, so it's up to either the TV or the network. it could also be the file being dodgy. Alternativley, if you're using AV receiver, you can set the audio / video delay if you're getting if for all files.
