Reply To: Playing Mkv Files Local Network

I’ve checked the Bravia manuals and Mkv is supported by both USB / DNLA.

Okay. What codec format do these MKV files contain? You might try installing MediaInfo; it is very good at identifying the properties of media files.

Out of curiosity, were the USB and DLNA support lists identical?

Back to your OP; where does BubbleUPnP fit into this? Are you using BubbleUPnP as a DMC, instructing WMP acting as a DMS to stream to your TV acting as a DMR? Or are you using WMP as DMC and DMS?

Can you install apps on the Sony?

Google and the Synology manual should help…
