​Well, upgraded earlier to 0.29 and it still does not work..  This is
getting frustrating at this point - I will be gone all next week and need
to link to plex to watch remotely..  I guess I'll have to look at the code
to see if I missed a setting it is chekcing for somewhere..  I never
remember having to set anything to run SystemEvent jobs though..

Not to mention 0.29 has some weird issues that I do not have time to
troubleshoot (like watching a recoding and having it blink in block with a
live tv channel I am not even watching - best I can describe it) - weird
thing is I can screenshot it from the API and it only shows the
recording..  I hgave no idea how I have a live basketball (HDHR - CBS) game
blinking in and out (which no one absolutely tuned) of a recording that was
on an HDPVR (whose lineup does not even include ATSC US channels...?).
What is really strange is that I just did a packet capture and the stream
is not even going to mythtv.  Of course, I just stopped and restarted
watching the recording and it is gone.  This is all for another topic
though :)

I might just roll back since 0.29 did not fix my immediate issue.
