I've done my best to provide English subtitles (click the "CC" icon at the bottom of the screen).

If anyone can assist in translating those mysterious phrases, please provide details in Comments and I'll edit the subtitles to include them.

Interviewer is Eric Lipman (with thanks to lhiram23 for identifying him).
