I did see on the Mythtv Forum that someone got it working on a P5 with
Ubuntu and RPI OS

Mostly it on the Pi 4/5 MythTV works out of the box after compiling mythtv
from sources, I wrote a bit more here. The Pi 5 is noticeably faster than
the Pi 5.

Don't forget to buy the heatsink, the official heatsink/fan is really good,
there was a review on it compared to other solutions and it came out as the
best. After I got the heatsink, I overclocked it a bit, didn't really have
to, but why not, right?

https://forum.mythtv.org/viewtopic.php?p=26986#p26986
(pasted below)

On the Raspberry Pi 4, eventually things stabilized to the point where it
was usable as one of my primary MythTV frontends which I used daily. The
jump forward and backwards and menu system were a bit laggy, but everything
was usable.

I upgraded to the Raspberry Pi 5, after compiling v33 mythtv from the
source, everything just worked smoothly out of the box with no tuning, no
overclocking, menus responsive, jump forward and backward was quick. But
since I had adequate cooling, I am running the Raspberry Pi 5 overclocked
from 2.4Ghz to -> 2.9Ghz. Unfortunately, 3.0Ghz wasn't stable for me and
kept crashing. Also I am not running 4k since my TV is just HD 1080p.

I have it up and running. I'm connecting via home wifi. Playback of MPEG2
drops frame and occasionally drops audio. I'm using the V4L2 decoder, and
oddly enough, LiveTV is better than playing back recordings.

Try using it wired ethernet and see if the frame drop goes away.

Actually I changed the audio readahead to 500ms. That seems to have worked.

Where did you change this at?

Setup -> Video -> Playback -> Advanced -> Audio read ahead.

If anyone can guide me I’d appreciate it lots

Despite suggestions from Gary I made no progress
So I flashed the ubuntu image
*everything worked
but building, with a fan heatsink, had CPU temperature over 80C and throttling. Monitoring build on raspberryan I did not see over 63C. On idle the case runs HOT
So I tried to build on RockPi 5.
ansible hangs forever
I thought to install prebuilt. I’ve never used PPA but followed the wiki (https://www.mythtv.org/wiki/Installing_MythTV_on_Ubuntu)
