From OCAU Wiki
MythTV is a free and open source Personal Video Recorder (PVR) for the Linux OS. It's easily extended through a diverse range 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 0.21.
- Display digital, high definition and analogue television
- Time-shift Live TV (Pause, Rewind and fast forward)
- Schedule programme recordings from an integrated Electronic Programme Guide (EPG)
- Automatically skip commercials
- Be skinned and extended through the plug-in system.

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)
- MythAppleTrailers (Stream the latest movie trailers direct from Apple)
Hardware support is largely dependent on your expectations of the system.
High definition playback requires more power than standard definition. Advanced features such as transparency, commercial skipping, and transcoding can all take up additional system resources. You will need to consider what the purpose of your system is going to be in order to work out the hardware required.
For that reason, a lot of the information here is a guide only.
- Searchable PVR Hardware database
- Official MythTV documentation hardware recommendations
- MythTV & High Definition...minimum requirements
- Official MythTV wiki - Configuring HDTV
- Information about X-Video Motion Compensation (XvMC)

Supported TV tuner adapters
Any TV tuner adapter utilising these chipsets should be fully supported by a recent Linux kernel.
- Conexant 2388x (Recommended)
- Brooktree878 (Recommended)
- Philips SAA 7134
- B2C2 Flexcop II

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, PCLinuxOS 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.

Distributions listed in alphabetical order.
- KnoppMyth is my attempt at making the Linux and MythTV installation as trivial as possible.
- Mythbuntu is an Ubuntu derivative focused upon setting up a standalone MythTV system similar to KnoppMyth or MythDora. The Mythbuntu distribution fits on a single CD which can also be used as a frontend liveCD.
VDPAU support (adding full GPU based decode to MythTV on Nvidia Geforce 8xxx and later GPUs) can easily be added to Mythbuntu (or a vanilla Ubuntu) using John Avenards patched repositories http://www.avenard.org/media/Ubuntu_Repository/Ubuntu_Repository.html WARNING: If the Avenard respositories are used no support is given by the Mythtv team as this is considered a code fork.
- 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)
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.

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:
- Exit mythfrontend and mythbackend
- Enter mythtv-setup
- Go to card options
- Select your DVB card
- Go to 'Advanced Settings'
- Select 'Recording Options'
- Check the box that says 'Record in TS format instead of PS'
- Exit mythtv-setup, and restart mythbackend and mythfrontend
Garbled / very quiet sound regardless of channel
Symptoms: No sound, very hissy sound, garbled sound but very quiet
Fix: set up the tv card to record in stereo rather than 5.1 audio.
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.
- Stop mythbackend
- Run mythtv-setup
- Select Option 4. Input Connections
- Add a starting channel (ie. 7)
- Close myth-setup, restart mythbackend and test
Full scan does not pick up channel 9
Symptoms: None of the channel 9 transport streams are tuned in after doing a full channel scan.
- Stop mythbackend
- Run mythtv-setup
- Select Option 5. Channel Editor
- Then go to Transport Editor
- Select (New Transport)
- Setup using the following settings
- Standard=DVB, Freq.=191625000, Bandwidth=7MHz, Inversion=Auto, Modulation=QAM-64, LP Coderate=None, HP Coderate=3/4, Trans.Mode=8K, Guard Int.=1/16, Hierarchy=None
- Do a full rescan of channels and channel 9 should be present
- Close myth-setup, restart mythbackend and test
Channel 9 and GO! No Longer Record
After the new channel GO! 99 was launched, something hinky happened to the channel. If your Go! and Nine recordings appear to record, but don't actually write to the hard disk, you will need to run mythtv-setup and re-scan them.
