Now that I have this working I'll document for others.

Hardware:

Canakit Raspberry Pi 4 Starter Kit.

GANA Micro HDMI-to-HDMI adapter

GeeekPi Acrylic Case for Raspberry Pi 4 Model B, Raspberry Pi Case with 
Cooling Fan & 4PCS Heatsinks for Raspberry Pi 4 Model B(Only for Pi 4) 
(Black and Clear)

StarTech.com SATA to USB Cable - USB 3.0 to 2.5” SATA III Hard Drive Adapter

Samsung 860 QVO 1TB Solid State Drive

NOTE the Canakit case was too thick where the Micro HDMI are so the GANA 
adapter would not connect reliably. So I uses the GEEEKPi case which is 
completely open on the power and micro HDMI connecters. If using GeeekPi 
case, use their CPU heatsink and not the Canakit one.

Software:

Raspbian Buster desktop but without apps. After OS install I moved the 
rootfs to the USB/SATA SSD using a script found 
here:(https://forum.mythtv.org/viewtopic.php?f=46&t=3232&start=15#p15884)

mythtv-light for v30

After installing mythtv-light per wiki. I use a script to install 
mythweb, mariadb and other backend related packages using a script I 
found herehttps://forum.mythtv.org/viewtopic.php?f=46&t=3232#p15773()

Configuration:

Setup Raspbian to operate at 1080P on my 4K TV.

Configure mythtv-setup for my HDHR tuners as any backend is configured

Create $HOME/.asoundrc file for Digital Audio with ALSA per 
https://www.mythtv.org/wiki/Raspberry_Pi

Configured mythfrontend using setup wizard for Audio- 
ALSA:mythtv:CARD=ALSA, Video- OpenMAX normal. Selected Mythbuntu 30.1 theme.


That's it.  Works fantastically at recording shows on multiple tuners 
while watching previously recorded show.

Note use the fan regardless of which case you pick.
