The case was referred to the Queens district attorney's office by police in Illinois who say they found two child-porn videos in an Internet file-sharing program the DJ was using in February.
Police say one video shows a four-year-old girl having sex with a man and the other gives advice and examples on how to sexually abuse minors.
Prosecutors say the 29-year-old wedding and party DJ is charged with possessing and promoting child pornography. He was arraigned yesterday and is being held on $100,000 bail.
The DJ could get up to seven years in prison if convicted.
