thinking the user is changing the chan-
nels via the receivers remote control.
You can construct your own IR-blaster if
you’re moderately handy with a solder-
ing gun, or you can purchase a pre-
assembled IR-blaster at a minimal cost
from [7].
The current version of KnoppMyth
(R5B7) has an option to configure an IR-
blaster. Unfortunately, this feature does
not work correctly. To remedy this, Greg
Frost has posted a work around in the
mysettopbox forums [8].
An out-of-the-box solution to this
problem is in development for the next
release of KnoppMyth.
In a nutshell, you will need to create a
second instance of LIRC or some equiva-
lent script to run at startup. You will
then need to create a script that will
change the channels on the receiver. Dif-
ferent cable/ satellite boxes will require
slightly different configurations, depend-
ing on the manufacturer make and
model.
For non KnoppMyth setups, you can
follow the guide at [9], which is fairly
distribution neutral.
Day to Day
If you’ve familiar with Tivo or other
commercial DVR systems, the menus in
MythTV look very familiar. From the
main menu (Figure 3), you can go watch
live TV, schedule upcoming recordings,
and go into the different add-on applica-
tions.
When watching live TV, you can pull
up the system menu with the m key and
browse what’s on other channels. You
will then be able to view the transparent
on-line guide while your show is still
viewable. You can scroll right and see
what will be the channel you’re cur-
rently viewing. You can also move up
and down to see what’s on the other
channels. This is similar to viewing pro-
gramming guides on a digital cable or
satellite system.
Scheduling recordings is very easy. Go
into the Schedule Recordings menu item
and browse the program guide. The da-
tabase typically holds two weeks worth
of programming information, so setting
up recordings for while you’re on vaca-
tion shouldn’t be a problem.
You can also find a particular show by
using the search function. When you se-
lect a program to be recorded, you have
the option of making it record at regular
intervals (similar to the season pass fea-
ture in Tivo) or as a one time instance.
For setting up your audio collection,
you start by listing the default directory
where your audio files will reside
MythTV/Utilities/Setup/Media Settings/
Music Settings. You can then copy your
music collection into the music directory
remotely via SSH or fish in Konqueror.
You can also rip and encode new CDs
by selecting import CD from the main
music menu. You have the option of en-
coding your ripped songs to either OGG,
MP3 or FLAC. You can also create music
play lists or have MythMusic play ran-
dom songs. MythWeather will display
Figure 3: MythTV provides a simple and practical main menu for
managing media content options.
Figure 4: The MythWeather add-on offers weather information cour-
tesy of the Weather Channel.
Figure 5: MythWeb lets you connect to your MythTV box from over the Internet.
