I've just upgraded to MC16 from MC15, and unfortunately I've uninstalled MC15 - I didn't test MC16 thoroughly enough.
But am now going to reinstall MC15 and attempt to restore its directories from a backup.
Anyway, the problem is that my WD TV Live doesn't seem to be cooperating with MC16. It all worked last weekend with MC15, but now doesn't.
It will play audio that I send to it and it also plays the audio of any video that I send to it. That was the basis of my "testing", I thought it was all working. But I hadn't actually switched the TV on to see what the WD TV was displaying.
Regardless of whether it's audio or video, the WD TV Live remains at its top level menu. It doesn't go into Now Playing for audio and it doesn't actually play video.
I am using Plugplayer on an iPad but to eliminate this, I also tried controlling the WD TV Live from within MC itself by selecting the WD TV Lice as a zone under Playing Now, but it has the same symptoms.
There have been no firmware upgrades to the WD TV Live in the last week.
