Piotr,

I have run a few tests on Minimyth2, once over the initial startup 
problems with upnp, more of that later, it works well.

I have two mythbackends on different subnets, one built from source, the 
other from ppa:mythbuntu/30 (i.e. current master), running under Xubuntu 
16.04 LTS (HWE).

SD card image generated using bsdtar running as root ( sudo su) on 
Xubuntu 16.04 LTS (HWE) - note that bsdtar  and f2fs-tools packages have 
to be installed.

  I made to changes to /boot/config.txt  for my TV UK 50Hz 1080p, with 
no overscan, plus MPG2 licence code, before inserting SD card into RPI2 .

hdmi_group=1
hdmi_mode=31
disable_overscan=1

On booting Country/Language screen was presented, defaulted to US, 
changed to UK, then the problems started on Mythtv Servers screen with 
"Loading..." being displayed continuously - it never timed out and I 
could get no response to any key presses.
Went in via SSH and rebooted, same issue.
Turned off upnp on the router for the subnet, rebooted and then the 
single mythbackend was found, so I clicked Save - nothing happened, so 
rebooted again.
This time I used manual to set IP address and password (note password is 
NOT 'mythtv', it is the random 8 character alpha-numeric generated when 
mythtv-backend was installed, this time mythfrontend ran (config.xml 
file was created in /home/mythtv/.mythtv/).

Using Setup Wizard, set Audio to OpenMax:hdmi, no sound from speakers, 
then set video profile to OpenMAX normal, ran the SD test video, which 
worked, I could get sound by using Volume UP key.
I then set Audio Mixer device to OpenMax and sound was then ok on 
speaker test.
 From then on things worked as expected.

There is definitely a problem with upnp detection on first run. I ran 
mythtv-light frontend on Raspbian Stretch and the mythbackend was 
automatically found.

I also checked mythfrontend log in /home/mythtv and it entries :
2017-11-23 11:49:44.028244 I  Assumed character encoding:
2017-11-23 11:49:44.028292 W  This application expects to be running a 
locale that specifies a UTF-8 codeset, and many features may behave 
improperly with your current language settings. Please set the LC_ALL or 
LC_CTYPE, and LANG variable(s) in the environment in which this program 
is executed to include a UTF-8 codeset (such as 'en_US.UTF-8').

I setup locale to en_GB.UTF-8, which removed the entries.

Also set timezone to Europe/London (it was UTC, +0000) and keyboard map 
to uk.

I don't know if setting locale and  timezone are really necessary for 
just a frontend.


And finally consider adding two packages to the MiniMyth2 image dialog  
and wpa_supplicant this will allow USB WIFI devices to be used without 
having to install over ethernet first, wifi-menu is already present. I 
do use WIFI.
