Ask HN: What is the first Bitcoin video on YouTube?

Youtube research is a nightmare. I am trying to use 'site:youtube.com bitcoin' in Google, and customising the date range, but there are so many false positives.

I have this one (15 nov 2010): https://www.youtube.com/watch?v=AiGCuyRJe8s. But not sure this is THE first one.

Is there a good technic to properly search Youtube videos ?
