  • Added auto discovery of MythTV servers/frontends
  • Added new 'watched' flag for recordings which can be set manually or automatically and optionally increase auto expiration priority for watched shows. Includes a new 'watched' icon in the frontend and in MythWeb.
  • Improved Jump to Program feature while watching a recording. This action will now bring up the Watch Recordings screen for selection of the program.

  • Added support for New Zealand MHEG profile
  • Added EPG support for Premiere's Optionskanaele
  • Added an optional idle timer to LiveTV. If we haven't received any remote/keyboard input for X minutes then we show a dialogue asking if the user is still watching. After 45 seconds without any reponse, we exit LiveTV. If the user responds, then the timer is reset.
