It might be a firmware version issue with the replacement unit (depending on manufacture date it may have been shipped with older firmware, mythtv requires a fairly recent version due to tuner locking mechanism changes). Goto the built-in webpage for the HDHomeRun Connect Duo and check the firmware ...

I run full mythtv (frontend & backends) V31 on both Pi3 and Pi4 (4GB) and they don't freeze/lockup.

On both systems, root file system is on SSD, so the micro SD card is only used for boot.
I have also run with root file system on normal spinning Hard Disks, again no lockups.

With Pi4 connected to your AV receiver and mythfrontend playing Live TV you can ssh into the Pi4 from another linux machine and see what the following 2 commands report: tvservice -s tvservice -m cea The first command should report current screen setting, the second will report all possible screen s...

Jim, Yes there are differences on in HD and 4K behavior. For background on why the pi_mythfrontend.json file is required (created by run_mythfrontend.sh) see https://lists.gt.net/mythtv/dev/629820#629820 It should only force 1920x1080@60Hz if /boot/config.txt contains the appropriate hdmi_group=1 an...

Jim,
Thanks, I have updated the script on github repository.

Mike.

One item of note is that metadata lookups on recordings failed, traced this to requiring python3-requests-cache to be installed, did that and all is good, so may need a tweak to the script. python3-requests-cache issue is fixed in mythtv-light v31 build 31.0-54-g445cf1fe6b This build contains quite...

I think your problem is as described in trac ticket https://code.mythtv.org/trac/ticket/13577 and mythtv forum post https://forum.mythtv.org/viewtopic.php?p=17769#p17769 It seems to be another mysql 8 issue, the forum post does have a potential fix in terms of a patch (I have not tried the patch), b...

Upgrade to mythtv 31, mythtv 30 has a problem with dvb-c (for background see https://forum.mythtv.org/viewtopic.php?f=36&t=3338&p=16190&hilit=mythtv+30+dvbc#p16190) As you are on Ubuntu 18.04, the upgrade is in a terminal session: sudo apt-add-repository ppa:mythbuntu/31 sudo apt update sudo apt upg...

I am using Kodi 18.6 with addon pvr-mythtv 5.10.15 If you change channum on mythbackend (Channel Editor or mythweb) Kodi needs to be restarted to fetch the updated information,otherwise it will use its cached data until the next periodic update, which defaults to 120 minutes after Kodi has been star...

As a guess as you have not mentioned either mythtv version or operating system.

If running *ubuntu 18.04 see https://lists.gt.net/mythtv/users/625986#625986

This solution is mentioned in Software Install section of https://www.mythtv.org/wiki/Installing_MythTV_on_Ubuntu

Have you got Storage Groups for Cover Art, Fan Art, Banners set using mythtv-setup Storage Directories?

Edit: the above is for metadata

One thing I just noticed in latest log is v4l2-dec, try using V4L2 Acceleration instead of V4L2 acceleration (decode only), again with 4 CPUs

Jim, Both of those files playback ok on my Pi3. I suspect the reason you are seeing Deint: None on Pi3 for test_1080i and test_720p is that Codec/Dec shows MPEG-2 v4l2. Both of the files are mpeg2. mike@myth-server-1:/myth/mythtv/videos$ mythffmpeg -i test_720p.ts ffmpeg version 4.2.1 Copyright (c) ...

Jim, You log file is showing a number of : 2020-04-07 11:18:33.174968 I [1390/1390] CoreContext mythplayer.cpp:789 (OpenFile) - Player(0): Opening 'GetPlaybackURL/UNABLE/TO/FIND/LOCAL/FILE/ON/raspberrypi/10501_20200407151832.ts' I do not see this on my Pi3. Is your configuration on Pi3 just mythfron...

Jim,

I have added a basic check in run_mythfrontend.sh that tests for drm presence (indicates dtoverlay=vc4-fkms-v3d has been enabled).
It exits with a message to run raspi-config, if drm is not found.

As you have have cloned pi-utils, to get the latest version. Mike
