MythTV is a free and open source Personal Video Recorder (PVR) for the Linux OS. It's easily extended through a diverse of plugins providing extra capabilities such as DVD playback, photo management and games. MythTV provides high levels of customisability and features far beyond those offered by equivalent Home Theatre PC (HTPC) applications. It utilises a unique client/server architecture allowing for flexible deployment in the home environment. The latest stable release of MythTV is 0.20.

MythTV can

  • Display digital, high definition and analogue television
  • Time-shift LiveTV (Pause, Rewind and fast forward)
  • Schedule programme recordings from an integrated Electronic Programme Guide (EPG)
  • Automatically skip commercials
  • Change the appearance of the display
  • Support multiple combinations of TV tuner adapters
  • Be extended through plugins

MythTV can not

  • Wash your undies
  • Clone your cat
  • Help with the development of a flux capacitor
  • Be described as anything less than brilliant

Plugins

MythTV is easily extended through a variety of plugins. A complete list of official MythTV plugins with a short description of their functionality have been catalogued below.

  • MythArchive (Create DVDs of your recordings)
  • MythBrowser (Built in web browser)
  • MythDVD (DVD/VCD playback and ripping capability)
  • MythFlix (A netflix implementation for MythTV)
  • MythGallery (Photo management and presentation)
  • MythGame (Play games on your television)
  • MythMusic (Music library management and playback)
  • MythNews (Read RSS feeds on your television)
  • MythPhone (Receive and make phone calls)
  • MythVideo (Playback for a variety of video formats)
  • MythWeather (Display weather information)
  • MythWeb (Web based management and video/audio streaming)

Supported and recommended hardware

The Linux kernel and MythTV support a large variety of hardware configurations. Historically, MythTV was developed for use with analogue television. Fortunately, support for Digital Video Broadcasting (DVB) was eventually included, providing MythTV with the capability to receive digital and high definition television.

When selecting hardware for use in your MythTV computer, it's important to establish the purpose of the project. That is, do you intend to play high definition television, or standard digital? This will ultimately determine the minimum hardware requirements for your MythTV computer. Obviously, high definition playback will require a more powerful computer than that of standard digital.

Lastly, you should check to ensure that your desired hardware is compatible with Linux and MythTV. To help with this process, the following supported devices have been listed. If in doubt, consult Google or the OCAU MythTV General Discussion and Support thread.

Minimum hardware requirements

It's important to understand that this topic is largely subjective. Individuals have different expectations and experiences that ultimately affect their perception of "minimum requirements". Therefore, the author of this section encourages you to use this information as a guide only.

Unsupported tuners

A list of confirmed unsupported tuners in alphabetical order
Adapter Details
DViCO FusionHDTV DVB-T Dual Digital 4 A relatively new device, it utilises the Zarlink ZL10353 chipset. Unlike its predecessors, this chipset is currently unsupported. Fortunately, driver development is active. Until a mature driver has been produced, it's recommended to stick with an adapter based on either bt878 or cx2388x.

Supported remote controls

MythTV supports any input device that can be configured with the Linux OS. This allows for a large selection of potential remote controls, wireless keyboards and any other input device you can conceive. People commonly associate remote controls with their televisions and HTPC's. As a result, this section provides information on supported Linux Infra-red Control (LIRC) devices. For a complete list of supported devices, you may like to look here.

Recommended Software

MythTV is an application that sits on top of a Linux distribution. Consequently, it's irrelevant which distribution you decide to use in your MythTV configuration. What's important is that you have the required package dependencies, and access to support. Distributions such as Ubuntu and Arch include MythTV in their package repositories which automatically resolve dependencies, simplifying the install process.

When choosing your Linux distribution, the author of this wiki article encourages you to pick a distribution that you're familiar with. Familiarity leads to confidence which is of benefit in a first-time install process. If you don't favour any particular distribution, pick a one that has a wide range of support. As a general rule of thumb, popular distributions are your best bet. They usually offer multiple places for seeking help such as forums, IRC and a mailing list. If you'd like assistance from other OCAU members, you may be interested in the MythTV General Discussion and Support thread on the OCAU forums.

Lastly, there are special, customised distributions that are designed specifically for MythTV. They present considerable advantages for users with little or no Linux experience by including automated installers and support for proprietary drivers. They're often considered "out of the box" solutions.

MythTV distributions

Distributions listed in alphabetical order.

KnoppMyth

  • KnoppMyth is my attempt at making the Linux and MythTV installation as trivial as possible.

MythDora (Recommended)

  • MythDora is a Fedora Core and MythTV "All-In-One" DVD. The DVD will load a preconfigured Fedora Core installation on your computer as well as install and configure MythTV.

Electronic programme guide (EPG)

A screenshot of a relatively standard MythTV EPG.

MythTV uses XMLTV to store and display programme data in the Electronic Programme Guide (EPG). Programme data is populated into the MythTV database through the use of a XMLTV grabber, such as the tv_grab_au script. In Australia, there are several XMLTV grabbers which provide varying levels of programme data. The legality of some grabbers are disputed.

Australian XMLTV grabbers

Shepherd (Recommended)

Shepherd provides reliable, high-quality guide data for Australian free-to-air TV and Pay TV channels by employing a flock of independent grabbers and data sources. In addition, Shepherd provides HDTV programme data, as well as the capability to automatically configure TV network icons. It's the de facto choice of OCAU MythTV users, and recommended by the author of this wiki article.

IceTV

IceTV is a commercial entity that provides pre-compiled programme data for subscribers. Subscription can be purchased for approximately $13/month.

OzTivo

OzTivo is a community maintained television guide that provides pre-compiled programme data in the XMLTV and TiVo slice formats. The Guide relies on a community of users to create and upload guide data to the Guide's database. The database is then hand-edited via a web interface to correct any mistakes.

ltd73 (tv_grab_au)

Prior to Shepherd, Ltd73's tv_grab_au script provides verbose and accurate programme data from the Yahoo7 web site. This script is now deprecated, and Australian MythTV users are encouraged to use it's successor, Shepherd.

Australian television network icons

MythTV provides users with the ability to define icons for individual TV channels. You're able to set these automatically with software such as Shepherd, or manually by configuring icons via mythtv-setup. There are numerous free-to-air icon schemes available from a variety sources. Some OCAU members have created useful TV network icon resources.

MythTV supports amongst other formats, JPEG and transparent PNG images. Unfortunately, it does not support SVG.

Getting icons

There are four OCAU-centric locations that you can get TV network icons.

  • Australian TV Network Logos
    Has a number of TV network icon schemes (mostly scalable versions of the schemes below.) Also has a master SVG template for editing your own icons.
  • Shepherd
    Automated channel icon schemes.
  • MythTV
    Dedges's cartoonish blue and grey icons.
  • FrogBoy's icon set

Configuring icons via mythtv-setup

  1. Run mythtv-setup, from either a terminal window or a run dialog.
  2. Go to 5. Channel Editor.
  3. Select the channel you wish to add an icon to.
    Note, you will need to press enter after you select the channel name. Double clicking seems to have been disabled for some reason.
  4. Enter the path to a supported graphic file in the Icon: field.

Tips, tricks and common problem fixes

Tips and tricks

For a comprehensive list of MythTV tips and tricks, you may like to visit the Myth(TV)ology web site for additional information.

Common problem fixes

No sound on Channel Seven or SBS

Symptoms: No sound occurs on channel Seven or SBS (In Australia, they have ac3 audio streams) when they are tuned to from another channel (i.e. You are watching channel nine, and change to channel Seven). There is however sound if you choose channel Seven, exit live TV mode and then re-enter live TV.

Fix: It appears there can be weird problems like this when using PS format to watch TV. It can be fixed by:

  1. Exit mythfrontend and mythbackend
  2. Enter mythtv-setup
  3. Go to card options
  4. Select your DVB card
  5. Go to 'Advanced Settings'
  6. Select 'Recording Options'
  7. Check the box that says 'Record in TS format instead of PS'
  8. Exit mythtv-setup, and restart mythbackend and mythfrontend

No display when watching LiveTV

Symptoms: When trying to watch LiveTV the screen is blank and no input is accepted, after a few moments will drop back to main menu.

Fix:

  1. Stop mythbackend
  2. Run mythtv-setup
  3. Select Option 4. Input Connections
  4. Add a starting channel (ie. 7)
  5. Close myth-setup, restart mythbackend and test
