Hi, hoping someone has an answer or can point me in the right direction.

I have a Sony KDL-24EX320 which so far plays everything stored on my server and delivered perfectly well through Mezzmo. However, I have a Sony Blu ray player BDPS390 which cannot play some of the files which the TV can handle. I'm getting the error "file is corrupt or not supported".

I know the file is not corrupt and is supported as the Sony TV plays it, as does my Panasonic Viera. I've experimented with all the various Sony profiles available in the Mezzmo software, all with the same results.
Transcoding for all devices is switched off, and I've also experimented with the advanced options - currently set as always deliver.

Any help would be most grateful.
