Time.png Outdated: Starting with 0.24, MythTV now has a dedicated 'demo tuner', and this is no longer the proper manner to set it up.

For people who require a tunerless backend, are developing in a Virtual Machine or are on a test-only system you will not normally be able to or need to access a tuner which limits alot of the development and testing you can do.

Below describes how you can add a dummy tuner just for the purpose of getting guide data in, you will not be able to play this back in LiveTV or record from this.


  • Create a valid MPEG2 file on the machine.
  • Create a new capture card
    • Set the Card Type to 'MPEG-2 encoder card (PVR-x50, PVR-500)'
    • Set the Video Device to the location of your MPEG2 file
  • Create your video source as normal
    • You may choose to use "No Grabber" or "Transmitted guide only (EIT)" (if you don't want listings for it)
  • Connect Inputs
    • Connect the video source to the input
  • Add new channel(s)
    • Use "Fetch channels from listings source" in "Input Connections" or
    • Create channels manually using the channel editor (ensure you add an XMLTV ID if you want listings)
  • Gather listing data as per normal
