Although the specifications claim that this system has no fans and is passively cooled, my first disapointment came when I opened the case to remove the 320G HDD to replace it with a Solid State one. There *was* a fan on the CPU. After powering on the system it immediately started blowing! Not a lot of noise but not what I expected from a "passively cooled" system.
Mythfrontend installation
Installation is straight forward, boot from mythbuntu 16.04 ISO (I use
Multiboot to boot from an external HDD containing several ISO's)
Hostname: mythtvfrontendBR
user: myth
password: mythtv
login automatically
Installation type: frontend
VNC en SSH enabled
Remote: Hauppauge TV Card
(disable generate options)
Video driver Nvidia (this is important because I want to use the power of the ION chipset which is able to play Full HD were the Atom is not powerfull enough)
Network settings
I prefer to give the frontend a static IP:
IP/NM/DG: 192.168.2.3 / 255.255.255.0 / 192.168.2.1
Backend settings
After first startup, the page with language settings appear which is a sign that the frontend can not connect to the backend
First find the sql password on the backend server:
password for the the mythtv sql user can be found in
/etc/apache2/sites-enabled/mythweb.conf
(look for db_password)
Then edit the file
/home/myth/.mythtv/config.xml
on the frontend.

After spending a whole evening to find out why my video playback was choppy, I tried my other mythfrontend and it had the same choppy video. Turned out a network cable was bad. (I had replaced a switch in the house earlier that week and must have damaged a cable).
Audio
Open the alsamixer and set the master volume to 100%
Then op the frontend settingspage:
mythfrontend->settings->audio
And select this:
ALSA:dmix:CARD=Nvidia,DEV=
Video
mythfrontend->settings->video
video playback (make use of the nvidia chipset for playback instead of CPU)
Normal -> Vdpau high quality
Preferences
setup->video->playback->next
on playback exit: save position and exit
setup->video->Program Guide
Guide starts at channel: 6
remote receiver
USB irDA: Philips OVU4003/00
remote: Hauppauge (grey)
Setup remote controle is described in
this page
use setup->key bindings in stead of the web interface.
config files for lirc are in /home/mythfrontend/.lirc/
shutdown issues
When shutting down the machine using the mythtv menu, the system reboots. I tried *a lot* of options (disabeling acpi, unloading network before shudown, halt, poweroff, shutdown with all the options possible with no luck). I ended up with using a halt option in grub:
/etc/grub.d/40_custom
menuentry 'halt' {
set saved_entry=0;
save_env saved_entry;
load_env;
halt;
}/etc/default/grub
GRUB_DEFAULT="saved"
update-grub
create a shutdown script that mythtv uses (set it though the mythfrontend->settings->general)
/usr/local/bin/mythshutdown
#!/bin/sh
sudo /usr/sbin/grub-set-default halt
sudo shutdown -h now
Now the system shuts down, restarts (for whatever reason?!?) but then boots the halt option (which sets the boot to normal boot) end really shut down. If you power up the system, it boots normally.
Uploading ....
