* Automatic creation of movies. If you start a demo in startmovie mode
  you will end up having BMP's named geekmovieXXXXX.bmp in your
  Half-Life root dir. These can later be used in programs like
  VideoMach (http://www.gromada.com/VideoMach.html) to create movies.

* Timdemo playback support.

* Ability to playback demo both as playdemo and viewdemo. Viewdemo
  is a more advanced playback mode that supports slowmotion,
  fast-forward, pause, jump between frames and more. All in a GUI
  with a timeline.

* Ability to repair demos with playback on wrong map and stuck console.
  Half-Life have a serious bug which makes demos unplayable if
  multiple demos are recorded on more than one map. Another bug
  causes the console to be stuck throughout the whole demo.

* Ability to remove fade to black in demos. Now you can watch demos
  recorded under fade to black as if they were recorded normally.

  - Half-Life version of the demo.
  - Demo Version.
  - Network Version.
  - Map used in the demo.
  - Mod the demo is recorded in.
  - HLTV recording.

  and store it to disk.

  Note: Maps can be added manually.
