I have PMS installed and running for most types of media, but I can't get it to work with anything that wants to use tsMuxeR. This makes me sad because I really like to avoid transcoding whenever possible and I have many HD .mkv's that would benefit from the tsMuxeR path.
I grabbed the latest tsMuxeR binary from smartlabs, as the one included with PMS did not work right on my system. The new one doesn't seem to complain, but I still can't get any love. I tried 1.10.5 and 1.11.345.
I see lots of messages like this in the debug.log
[New I/O server worker #1-1] DEBUG 21:20:43.744 External inputstream instance is null... sounds not good, waiting 500ms
