Such a pity WDTV Live SMP can’t manage SRT via Media Server (DLNA)…
I have an LG DP1W and with both Mezzmo v2.4.x and J.River Media Center v17.x it’s possible.
For example J.River has options for DLNA subtitles, but for some reason WDTVLive SMP ignores them.
That wouldn’t be such an issue (everything works fine by USB or SAMBA) but using a REAL media server can make up for the many issues and lack of customization in the Media Library…
