As a note to the poster: The first video is not available where I live (Netherlands), maybe the link is wrong, the others are however.
This one works for me (UK):

I think they may have accidentally removed a character from the URL.
The posted URL: https://www.youtube.com/watch?v=2DIl3Hfh9t
The actual URL: https://www.youtube.com/watch?v=2DIl3Hfh9tY
Just adding: it is unavailable for me here in India too.
I would also recommend (8 lectures)
Leonard Susskind Topics in String Theory

Despite the name this is largely about general relativity and black holes and other horizons. The best detailed description of black holes for laymen (assuming you have algebra and basic calculus) I've ever seen.

To add to those
The Perimeter Institute ones
The Royal Institution ones
There's multiple of each devoted to cosmology and black holes in particular.
