I'm relatively new to Gentoo and I used the guide below to basically
install Mythtv. I posted this guide initially a few weeks back and several
members helped refine it. If you are installing just a frontend, then
follow steps 1, 11 and 12. If installing a backend then follow the entire
guide. I personally didn't install pulseaudio which happened automatically
since I didn't declare pulseaudio in make.conf or package.use. I added
media-tv/mythtv dvb to the package.use file to enable the use of my tuner
cards (Dvico and pcHDTV).

2/27/15 rev
1. Install the MythTV

# emerge -av mythtv

2. Enable and start MySQL

# emerge --config =dev-db/mariadb-10.0.16
# rc-update add mysql default && rc-service mysql start

3. You'll also need to check that the "networking" feature of MySQL is
turned on. Check that /etc/mysql/my.cnf does not contain skip-networking.
If it does, either remove that line or comment it out. Also verify that
bind-address is set to your IP address instead of 127.0.0.1. Alternatively
/etc/conf.d/mysql can be used to address skip-networking and bind-address.
Set MY_ARGS="--bind-address=masterbackendipaddress" and skip-networking
default is off. If you change either of these items, restart MySQL.

# rc-service mysql restart

4. Setup mysql and add a password:

# mysql_secure_installation

5. Create the database structure: (See example using root as user and 1234
as password)

# mysql -u root -p1234 </usr/share/mythtv/database/mc.sql

6. Update your database (Optional with new install): (See example using
root as user and 1234 as password)

# mysql_upgrade -u root -p1234

7. Add time zone tables: (See example using root as user and 1234 as
password)

$ mysql_tzinfo_to_sql /usr/share/zoneinfo | mysql -u root -p1234 mysql

8. Allow remote frontends access: (See example using mythtv as user, mythtv
as password and root as user, 1234 as password)

# mysql -u root -p1234
MariaDB [(none)]> GRANT ALL ON mythconverg.* TO 'mythtv'@'192.168.97.%'
IDENTIFIED BY 'mythtv';
***Query OK, 0 rows affected (0.00 sec)***output only!
MariaDB [(none)]> FLUSH PRIVILEGES;
***Query OK, 0 rows affected (0.00 sec)***output only!
MariaDB [(none)]> exit
***Bye***output only!

9. Enable mythbackend

# rc-update add mythbackend default

10. Setup mythbackend

$ mythtv-setup

If restoring a database backup, complete the General section only then
perform the database backup.
Example command:
./mythconverg_restore.pl --drop_database --create_database --directory
/home/username/Desktop --filename mythconverg-1317-20150227105348.sql.gz

11. Setup logging for mythfrontend and mythbackend.

A. Change permissions on /var/log/mythtv with chown for the user you are
running mythtv.

B. Edit /etc/conf.d/mythfrontend
Replace
#MYTHFRONTEND_OPTS="--syslog local7"
With
MYTHFRONTEND_OPTS="--quiet --logpath /var/log/mythtv"

C. Edit /etc/conf.d/mythbackend
Replace
#MYTHBACKEND_OPTS=""
With
MYTHBACKEND_OPTS="--quiet --logpath /var/log/mythtv"
*****This isn't needed due it is setup in the /etc/init.d/mythbackend

12. No icons/launchers, to start Mythtv frontend or backend are created.
Solution - KDE
Right click on KDE homerun icon and select edit applications.
Select Multimedia
Select new item
Enter Mythtv for item name
Enter mythfrontend for command
Select the empty icon window
Select other icons and then browse
Select mythfrontend photo
Select edit>sort>sort all by name
Select save and close
