Your help please! where can I find conversational video clips?

I hope you got my point, I need videos to download contains conversations or interviews between two people!

I thought I can find my target at CNN or BBC, but the proplem that appears that I don't know which kind of videos they are, I mean I don't know if this show is a conversational one or not ..

Of coures I need them available to download. Either with a direct link or with assistant software doesn't matter..

I hope from you that you help me as you helped me before..

( I need them quickly please, the time issue is so important)

Thank you all in advance
