The largest pirate video lab to be found in New York State was shut down by law enforcement authorities Tuesday. They seized approximately 4,000 unauthorized copies of many of the major studios’ top films.The raid, led by New York police and assisted by investigators from the anti-piracy unit of the Motion Picture Assn. of America, netted seven suspects and 304 videotape recorders. The machines were in the process of dubbing copies of animated pix “Aladdin, “”Cinderella” and “Beauty and the Beast,” currently three of the top-selling titles in the homevideo industry. Investigators also found bootlegged copies of “Sliver,”"Free Willy,”"Batman, “”101 Dalmatians” and “The Fugitive,” among others, along with more than 400 authorized copies of top films, ostensibly used to make the illegal copies. The MPAA estimates that the bootleggers were capable of creating more than 1. 25 million unauthorized copies annually. The facility is the second-largest unauthorized duplication facility uncovered in the MPAA’s 19-year history of anti-piracy operations. The largest was seized by the FBI’s Asian Anti-Crime Task Force in Fairfax, Va., in May 1993 .
