ShowShifter
ShowShifter, now obsolete, was a proprietary, commercial DVR (Digital Video Recording) and HTPC (Home theater PC) software for Windows.
ShowShifter offered features such as TV recording, PVR facilities, EPG, audio and video Jukebox, and a picture viewer from within a user interface designed to be used by a remote control at a comfortable viewing distance from the video display, hence the term 10 foot UI.
