Bharat or India: Which is correct? My interview in @ChanakyaTv

 Bharat or India - which was the original name of our country?

What do these names mean?
Any evidence to pinpoint the time we started calling our country by these names?
Is it right to change the name from India to Bharat?
Jambu Dweepe, Bharata Varshe, Bharata Kande... what are they? where are they?
Did the olden Tamil people recognize 'Bharat'?
How did we get the name 'Hindu'?
