MythTV

Tips on using the MythTV Backend app:

• Useful to run it as mythtvsetup --geometry 1024x720 so that you can see the messages in the launch window in the background (assuming your screen is larger than 1024x720)
• When connecting a source to an input (e.g. comcast to an HDHomeRun in my case), fetch channels from listing source only works *after* scanning for channels first
• If you want to use a separate front end, the database is called mythconverg and the user and password are both mythtv
• You have to explicitly tell Myth to add digital channels to the DB since they're almost always unusable without a scan

After installing mythtv-backend, open a terminal and run "sudo mythtv-setup --geometry 1024x720".

To navigate the menu use the arrow keys and enter to select.

Move to "1. General", and press enter.

1.1 Host address Backend setup Most of the options on the first page do not need to be changed. the local backend ip address and master backend ip address are the same if you are only running one backend. The value for them is the ip address of your hda ex. 192.168.1.19 or 192.168.2.87.

The security pin is only a 4 digit security code if mythtv is being run on a large LAN network. It is your choice if you wish to use it. If you don't set it to 0000.

Now move to the next page with the next button (Sometimes covered by gnome task bar it is the bottom most left button).

1.2 Locale settings TV format is NTSC for North America and Japan, PAL for most parts of Europe and everywhere else. The VBI format is whatever you selected for above. NTSC Closed Caption for NTSC and PAL Teletext for PAL.

The Channel frequency table is used if you are using a coaxial input for either antenna or cable. If you are using an antenna use a "-bcast" selection. If you are using cable select one that says cable with your country code. If you are unsure select "auto".

For your local timezone, input your local timezone. pretty self-explanatory.

1.3 Misc. Settings

Master Backend Override: I think this means the backend will move stuff if it finds things in the videos directory on its machine.

Follow Symbolic links...: means if there is a sym. link in the videos directory when you add or delete things it will treat it as a folder rather then a file.

Delete files slowly: umm... delete them slowly as to not kill your pentium II.

HD Ringbuffer: Size in ram that it buffers recordings so when playing they dont stutter.

Misc. status App: A script that adds custom info to the system status pages.

Disable Auto. DB Backup: This should never be checked unless you have your own sql backup strategy in place.

Disable Fire-wire Reset: Reset fire-wire bus when fire-wire recorders stop responding. Enable only if it causes problems.

1.4 EIT Scanner Options

EIT Transport Timeout: maximum time to wait on data before moving to next channel.

Cross Source EIT: Listing data collected on one source will be used on the first matching DVB channel.

Backend Idle...: time after the recorder finishes that the backend will go to get new EIT data.

1.5 Shutdown/Wakeup Options:

Startup command: a command run right after the Backend or BE is finished loading.

Block Shutdown before...: Will not auto shutdown until until after client connects and disconnects.

Idle shutdown time: time before myth shuts itself and all other backends off. 0 to disable.

Max. wait for rec.: if it is going to auto shutdown and there is recording starting in this time period it will stay on.

Startup before record: time before a recording that a backend is woken up.

Wakeup Time Format: time format of setwakeup command.

Command to set Wakeup time: umm...

Various allows: allow certain jobs to take place on this machiene.

1.9 Job Queue (Global)

Run Jobs on Original...: when doing an operations on a video, do it on the backend that recorded it.

Start commercial flagging...: do flagging at the same time as recording.

Commercial flagger command: should not be changed unless you are using your own commercial flagger.

Trans-coder Command: should not be changed unless you are using your own trans-coder.

run trans-code jobs...: do trans-coding before commercial flagging.

Save orig. files after trans-code: keep original file instead of deleting them after trans-coding them.
