Thanks again Mark!

That script is promising, but it looks a little complex to implement.

I see it's a few years old, yet hasn't been included with MythTV yet. 
Is that a bad thing?


You're right, I actually have an older version currently on our main TV 
(0.27.6+fixes20170114) stuck on mythbuntu 14.04.  However I've been 
writing questions here as I'm building a new MythTV box which has 
0.28.1-3 (2017-04-24).
