So on the RP3 B+, I used LibreELEC and TVH server/client and it sort of worked, but a big pain to setup each stop and it was not forgiving on signal issues in remote areas.

> Mike, I got your script from the mythtv forum that you referred me to.  It worked great on my RP3 B+.  As I commented there I’ve ordered a 4GB RP4.  I put some questions in the forum since there seem to be a crowd there who are interested. Since the RP4 doesn’t have MPEG2 HW decoder, I’m concerned that it might not be a good combined FE/BE.  If the RP4 works solidly as a BE, I can use my RP3 as  Kodi FE only.

 From my testing lack of MPEG2 HW decoder is not a problem as the 4 
cortex-a72 cores in the Pi4 are powerful enough for software decoding.

Note Kodi (17.6) from Raspbian Buster Repository does not work properly 
on Pi3 or Pi4.

Working version of Kodi 18 (pplware) for pi3 (do NOT install on Pi4)
