On the inside this is a:
Pegatron IPP7A-CP (Rev: 1.01)

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 9.10 ISO (I use Multiboot to boot from an external HDD containing several ISO's)

Hostname: frontend2
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)

Security pin 0000 (default)

host: 192.168.x.x (IP address of the Mythtv backend server) 
db: mythconverg
user: mythtv
password: MLW6EkdS


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).

Preferences

setup->video->playback->next

on playback exit: save position and exit

setup->video->Program Guide
Guide starts at channel: 6

WiFi

first option
After the initial setup with a cable I installed Wifi so I can place the system were I want.
The Medion system came with a separte USB Wifi dongle:
Bus 001 Device 009: ID 1d4d:000c 

second option
Because Ubuntu didn't recognized it, I replaced it with an Edimax EW-7711UMn
Bus 002 Device 011: ID 7392:7711 
I had used this device before on Linux and was sure it worked after blacklisting a few kernel modules in /etc/modprobe.d/blacklist.conf:

blacklist rt2x00usb
blacklist rt2x00lib
blacklist rt2800usb
blacklist ndiswrapper 

If these modules al already loaded, unload them with rmmod ore reboot you system before plugging in the Wifi device. 
(Note that ndiswrapper was blacklisted. If in the future you wish to use it, remember this.)

The WiFi netwerk should always connect without asking for a network password:
Login as root and start the netwerk manager: nm-connection-editor

Make a connection to the wifi network en check: "Available to all users"
If you don't want to waste time waiting for a DHCP request, give the connection a fixed IP address, netmask, DG and DNS server address.

third option
Because the Wifi signal was poor using the Edimax EW-7711UMn the streaming video was choppy. I replaced the dongle with a 1000mW WiFly-City device from Dealextreme. Now the signal is 98-100%! 

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/

startup delay mythfrontend

Add a small delay before mythfrontend starts at startup, because the wireless network needs some time to be functional.
Applications->Settings->Session and Startup
Tab application autostart
change MythTV Frontend to: /usr/local/bin/mythfrontend_delayed
create the script:
#!/bin/sh
# start mythfrontend after a delay so the WiFi network is up
sleep 10 
mythfrontend --service
chmod 755 /usr/local/bin/mythfrontend_delayed

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 al 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.
