If the names Gypsy, Tom Servo, Cambot and Crow T. Robot sound familiar, you know about Mystery Science Theater 3000 (MST3K). The premise was that Joel Robinson was trapped in space on the Satellite of Love by Dr. Clayton Forester and was forced to watch horribly bad movies, mostly science fiction stinkers. With the assistance of four robot pals, Joel (later replaced by the show's head writer, Michael J. Nelson) and the robots provided running commentary as the movie played. A large cult grew around the show.
After the show was canceled, some of the MST3K gang created RiffTrax. Nelson, Kevin Murphy, Bill Corbett and a host of guest riffers sell audio tracks (usually about $3.99 each) to be synced with movies, bringing the MST3K experience to a huge catalog of current films. By running the film in the DVD Player application, VLC, iTunes or a physical DVD player, and simultaneously playing the MP3 RiffTrax in iTunes or QuickTime Player (if iTunes is playing the film), the guys recreated the art of skewering movies for the current generation of bad movie enthusiasts.
Though the results are hilarious, syncing the RiffTrax to the movie is a challenge. RiffTrax tries its best to help by giving you a chapter listing of how the RiffTrax relates to the film. They even give you a DisembAudio robot narrator that repeats a line in the film every so often to help sync. This can be tricky when you're trying to figure out whether the movie or the RiffTrax is slower. If you want to pause the movie, you have to pause the film and the RiffTrax audio separately.
RiffSync solves this audio-sync problem and gives a few additional options to improve the movie experience. Read on for a full review of RiffSync.
