Just read a short interview with DA Pennebaker about No Direction Home. He says he didn't really notice the negativity of audiences. This is what he said when asked whether he really didn't hear the booing:

I hadn't noticed it. It's hard to tell booing from cheering in a way and I'm up there on stage so there's a lot of noise - I'm in the middle of The Band. Maybe I heard it and hadn't thought about it. It just didn't seem reasonable to me in view of how marvellous that music was.
