I am trying to play m2ts files, but I have also tried re-muxing to .mkv and even re-muxing the m2ts with only the main video and audio file.
I also tried re-muxing to m2ts with the audio stripped to the DTS core (having read there are issues with the WDTV passing DTS-MA)
All of these files played ok from a HD connected directly to the WDTV Live, but not from a network share.
