All good questions. Should have included that in my original post.
I'm running JS 27.0.26 (64bit) Windows
Playback appears to start, I get the control bar showing (backup, pause, ff, etc), and the timing shows 00:00 on the left and {len of track} on the right and then nothing. It does show the PAUSE button though, as if it's playing.
The timer doesn't change, no progress bar. etc.
JRAndroid is not hung though, if I press EXIT on my remote, it returns to prev screen and I can continue navigating.
Also, it DOES show up as a DLNA renderer, but when I try to send music to it, it switches to the playback screen, shows the control bar, len of track, etc, but then, nothing, Same as above. Even if I start from the player page.
One thing that's interesting, is that on my PC, when I select a song and SEND TO the jrandroid on the tv, the status bar up top on MC running on my PC shows the progress bar moving, as if it's playing, yet, right under the track name, it says "Waiting".
