TyShow is a codec that allows video files extracted from a modified TiVo to be played back in Windows using any program that supports the Microsoft Windows DirectShow multimedia framework. TyShow is not for playback of shows extracted from an unmodified TiVo using [TiVoDesktop]. TyShow plays files both standard definition shows from Series 1 and 2 TiVos and high definition shows from a Series 2 DirecTiVo; there is no Series 3 support at this time.


  • Any Series 1 or Series 2 TiVo
  • TiVo must be modified and recorded show Encryption must be disabled
  • Shows must be extracted from the TiVo to Windows PC, using a program on the TiVo such as [mfs_ftp]


  • Download the latest version of TyShow from the TyShow SourceForge download page.
  • Extract the files to a folder (such as TyShow-BETA-0.15) using 7zip or equivalent.
  • Move this folder to a permanent location, such as C:\Program Files\TyShow-BETA-0.15
  • Register TyShow with Windows by double-clicking the register.bat file in the TyShow directory.
