This is the ad: http://www.youtube.com/watch?v=gHGDN9-oFJE - be sure to have subtitles on (unless you understand Hindi). One interesting observation about the ad: the search results that the girl deems to be good and informative are almost all Wikipedia hits. It's actually pretty similar to my situation: Google is basically a better Wikipedia searching tool than what Wikipedia provides.
Two of my old buddies, one an Indian, the other a Pakistani, could completely understand each other, yet both insisted that they spoke different languages (Punjabi/Hindi and Urdu respectively)
Another friend of mind, who left Pakistan as a 10 year old, always just shook his head with a smile and said "Dude, that's like a guy from Alabama saying someone from England speaks a different language."
