General
Database Page 1
Hostname
Default Setting 127.0.0.1
On Page Description The hostname or IP address of the machine hosting the database. This information is required
Detailed Description and Comments If you are running a single combined backend and frontend, then leave this at its default value of 127.0.0.1. This is often referred to as the local loopback IP address. If you have multiple frontends connecting to this backend then you will need to set this address to the same address as the its real IP address eg 192.168.2.11 as it appears on your network. If you have a DNS Server running on your network you can just put the hostname eg "MythBackend". Your DNS Server will translate this to its real IP address.
Database
Default Setting mythconverg
On Page Description The name of the database. This information is required
Detailed Description and Comments This is the name of the database the MythTV backend uses to store information. Normally you should not need to change this. However, you may choose to have different databases for different reasons, for example, a test database so you can check out configurations, and then put this back to mythconverg later, or a different database depending on user, so each user can have their own look and feel.
User
Default Setting mythtv
On Page Description The user name to use while connecting to the database. This information is required
Detailed Description and Comments You should not have to change this from its default.
Password
Default Setting mythtv
On Page Description The password to use while connecting to the database. This information is required
Detailed Description and Comments Change this to suit your system
Database type

Detailed Description and Comments This is the meat of the subject
Use Wake-on-LAN to Wake Database
Setting Type Toggle
Default Setting Unchecked
On Page Descripti If checked, the frontend will use Wake-On Lan parameters to reconnect to the database server (Mythbackend)
Detailed Description and Comments Wake-On lan is an ACPI option that allows your machine to powerup based on activity on the network. You need to makes sure that your machine supports ACPI correctly for this to work. You can use this remotely activate your machine for instance when you are at work.
Audio
Audio output device
Default Setting /dev/dsp
On Page Description Blank
Detailed Description and Comments This is the sound card that you want to use.

To specify an ALSA device, use the format ALSA:device (where device is a valid ALSA device such as spdif; iec958; default; hw::0,0; plughw:0,0; etc.). For example, ALSA:spdif.
You can find out which ALSA devices you have available, with the command

Enable AC3 to SPDIF passthrough
Default Setting Unchecked
On Page Description Enable sending AC3 audio directly to your sound card's SPDIF output. on sources which contain AC3 soundtracks (usually digital tv). Requires that the sudio output device be set to something suitable
Detailed Description and Comments AC3 is Dolby Digital surround. You will need to connect your Myth box to your surround receiver via a Optical or coaxial connector. Raw AC3 Stream is passed through to your receiver which will decode the surround. This is the preferred method for best audio quality, and also takes the audio processing load from your machine.

For more information on setting up digital audio, see the Configuring Digital Sound page.

Agressive soundcard buffering
Default Setting Off
On Page Description If enabled, MythTV will pretend to have a smaller sound card buffer than is really present. This may speed up seeking, but can also cause playback problems.

Default Setting On
On Page Description MythTV can control the PCM and master mixer volume. If you prefer to use an external mixer program, then disable this option.

Monitor CD/DVD
Default Setting Off
On Page Description This enables support for monitoring your CD/DVD drives for new disks and launching the proper plugin to handle them.
Detailed Description and Comments This is the meat of the subject
Enable X-box Hardware
Default Setting Disabled
On Page Description This enables support for Xbox Specific hardware. Requires a frontend restart for changes to take effect.
Detailed Description and Comments Enabling this option will add another button to the settings menu allowing configuration of your Xbox LED. You will need the Blink program from the xbox-linux project, which is installed as /bin/led on GentooX and /usr/bin/blink on Xebian. (Type which blink to see if the program is available.) If you do not have blink, you may obtain it from the Xbox-Linux project site at http://xbox-linux.sf.net/.

Once you have installed blink you will need to set permissions. blink needs write permission to the i2c device to function properly. There are three methods to accomplish this. First, you could run mythfrontend as root, which is the simplest method, but could potentially be a security risk. Next, you may make the blink binary setuid root, which allows non-privileged users to run a program with root capability. This is done by typing the command:

   $ su
   # chmod u+s /path/to/blink

If you select GentooX as the distribution led will be used as the blink binary name, otherwise, blink is used. Colors should be self explanatory. The update interval determines how often the frontend should poll the backend to determine if the status has changed.
