I'm posting the link to these interviews because some may not have the El Rey network on cable, and might like to see them. I'm not sure what Robert Rodriguez plans to do with his series of The Director Chair interviews. I'd guess release some sort DVD package with them later, but who knows? It's a unique idea, and one of the better programming features to his El Rey network. I wish they were a bit longer, however, and a bit more detailed. But at least it's fun to see and hear what other director's have to say about their previous films.
From the looks of it, it appears the YT videos are bootlegged, in other words, I'd guess someone either taped them off the network or shot them from a cell phone off their TV screen as there's an annoying white glow in the middle of the frame. Still if you'd like to peruse them and check them out, the links are below.
