I have a question about the verb phrase "*click on*" [here](http://news.yahoo.com/tapes-missing-ny-boy-case-expected-court-062754174.html): 

> 
> ***After the videotape clicks on***, the 53-year-old calmly tells investigators how he choked 6-year-old Etan Patz in the basement of a Manhattan convenience store on May 25, 1979. He describes putting the boy, who was still alive, into a plastic bag, then putting the bag inside a box and dumping it nearby.

How does a "videotape click on"? I do understand a door "clicks shut" though. Did the writer mean "*after the videotape* ***player was clicked on***"?
