 The version that was released on home video in the United States by  VidAmerica (and also shown on cable television) is a much trimmed version.   All of the violence and nearly all of the sex is cut.  The most notorious  scene, where Emanuelle uncovers a couple making love while watching a "snuff"  film, is trimmed so severely that what is happeing on the film is barely  hinted at, whereas the original shows the torture film in graphic detail.
