Ok I think I might have narrowed it down. The appearing and disappearing of devices on the now playing tree issue does not appear to be caused by Whitebear, Network or LMS
I installed a portable version of MC17 on an external hard drive
1. Reset Whitebear
2. Devices including SB Touch and TV appeared.
3. Selected SB touch and began to stream music
4. Navigated other albums etc. no issues works as expected.
5. After stopping active streaming of music, the SB Touch went into idle mode. It began appearing and disappearing from tree view.
For me this isn't a problem. There are no issues navigating while I am actively listening anymore. I only lose the SB Touch if I stop streaming for a short while (30 sec to a minute)
However when using the standard install on my notebook. The constant appearing and disappearing of the DLNA devices ( regardless of their states ) from tree view makes MC17 streaming tedious.
The only thought I have is that I had an expired trial of MC 17.0.183 and I installed 17.0.189 licensed version over the top of it. The fresh install of MC17 (.189) on the portable drive is working much much better in this regard.
