I bought a Sony Camcorder HDR-XR550V from New York USA. It says camescope numerique HD = NTSC. Sony Camcorder HDR-XR550V is equipped with G series lens, 240GB hard disk, 3.5-inch LCD and EVF, headphone and mic jacks, and shutter and iris controls. But I have an apprehension that will it work is India? Is NTSC will be a problem? What is the purpose of NTSC in a camcorder? What is the meaning of camescope numerique. If anyone knows it please tell me.
