Mark,

The following maybe helpful on Raspberry Pi 4 with Raspbian Buster

Known Issues:

1. USB SATA converters for SSD/Hardisks, terrible performance or disk 
corruption

   See https://forum.mythtv.org/viewtopic.php?f=46&t=3221&start=15#p15760

2. WIFI Keyboards limited range

   There is a known issue with USB3 interference on some WIFI keyboards 
which limits the range to a few inches rather than many feet.

   A solution is to use USB extender cable and plug keyboard receiver 
into that.

   Note this issue is not just Raspberry Pi4, other systems have been 
known to have this interference problem.


Helper Scripts (also work on Pi2 or Pi3)

1. Move Raspbian Buster from microSD card to SSD/Harddisk

   See https://forum.mythtv.org/viewtopic.php?f=46&t=3232&start=15#p15884

2. Setup full mythtv backend

   See https://forum.mythtv.org/viewtopic.php?f=46&t=3232#p15773

   Note: assumes install location of mythbackend is /usr/

   If building locally default ./configure will use /usr/local/, unless 
--prefix=/usr is specified.

   mythtv packaging deb-light uses --prefix=/usr

   If install location is /usr/local the systemd mythtv-backend.service 
file needs adjustment.
