What are the inputs on back of iMac with lightening bolts
What are the two inputs on the back of my iMac that have lightening bolts for? Can they be used for inputing video? My camcorder has a DV output. Are they better than using USB? I have a new iMac that has a 2.9 GHz Intel Core i5 processor.
iMac, OS X Mountain Lion (10.8.2)
