Set it up once, and it's totally hands free operation throughout the day, the week or the month. The perfect addition to any overnight or long voyage passenger vessel because it provides entertainment for dozens of people yet requires no personnel for operation.
At the beginning of the movie session, load up the DVD or VHS movies that you want to show. Enter their titles and their running times in the computer. Then enter their show times and voila! You have a fully operational movie theater that will dim the lights right before the show, open the curtain, and start the movie. At the end, it will raise the lights back up in the theater for safe exit of the passengers, then announce the next movie and it's start time.
