I recently installed Mezzmo and I'm in the process of evaluating the software for purchase. I have a Sony BDP S390 and am unable to play .mkv files without transcoding. I verified the S390 will play mkv files running Serviio with a generic profile and transcoding disabled. In Mezzmo, I tried all the Sony BDP profile options and none would allow streaming mkv files. Some of the profiles allowed the S390 to see the mkv files but when I tried playing them the S390 said the files were corrupt. Since the S390 is perfectly capable of playing the files direct, it's a complete wast of disk space and CPU cycles to transcode the files while playing them.

Is there any way of playing the mkv files without transcoding? I saw a similar post on this exact issue from Jan 2012 but the post was for a different Sony BDP and a final answer was never given.
