LIRC
So the first step was to get LIRC up and running on Mythbuntu; this was quite easy as the default installation do enable lirc, I only selected " Enable an IR Transmitter" and selected a bogus Serial lirc device.
This created all the relevant configuration files.
I then searched the net for the lircd.conf (remote command reference file) for my spesific decoder
(DSD820 aka DSTV DualView Decoder).
I did not find the spesific file but found one for the UEC DSD910 decoder.
The DSD910 remote file (general.conf):
#

end remote
This file was copied to the relevant directory in /var/lib/cache/lirc/....
The next step was to change the config in /etc/lirc/hardware.conf
#Chosen IR Transmitter
TRANSMITTER="dsd910"
TRANSMITTER_MODULES="lirc_dev lirc_serial"
TRANSMITTER_DRIVER=""
TRANSMITTER_DEVICE="/dev/lirc0"
TRANSMITTER_LIRCD_CONF="dsd910/general.conf"
TRANSMITTER_LIRCD_ARGS=""
After that I started the lirc again:
sudo /etc/init.d/lirc start
This was then tested with the following command:
sudo irsend SEND_ONCE dsd910 information
This worked and showed the "information banner".
This was tested on TV1.
Still to do is to add and test TV2 ir and to enable a change channel script in Mythbuntu.

Bind Dynamic DNS Updates
I saw a request to update Bind via a command line rather than Webmin for the ease and speed of a command line; So I embarked on investigating this.
Firstly it seems that there is not a lot of dynamic update or command line update scripts available or the people just don't want to share ???
I stumbled across nsupdate, an application that is part of the Bind suite.
This is a command line tool to add dynamic updates to an DNS server.
for this to work you need to update the specific zone file with at least the following configuration:
zone "example.com" {
type master;
file "/etc/bind/example.com.hosts";
allow-update {192.168.0.0/24; };
journal "/var/lib/bind/example.com.hosts.jnl";
};
For dynamic DNS you need:
allow-update
journal
then to add an entry to the DNS server:
from within the 192.168 ip range :
user@pc:~$ nsupdate
> zone example.com
> update add guest1.example.com. 86400 A 192.168.0.10
> send
> quit
your syslog on your DNS server will log all updates
