I am trying to unsuccessfully rip dvds to my mac to put on my apple tv or iPad etc, but when I look at the dvd they are all corrupt with lines through them. I can't also load the VLC which everytime I load a dvd handbrake says cannot find. Do yo need the VLC working ? Can anybody help as you can se I am a pretty basic user so please put it in plain english so that I can understand your response.
