Actually, I watched the video. I didn’t detect much booing, more or less enthusiastic cheers. There may have been a few boos, but overall, she seemed to have been very warmly received. Listen and decide for yourself.

I think cheers clearly drown out any stray boos.
I have FOX News on TV as I sit here at the keyboard, they were just talking about the boos on their tape. Then talked about how stupid it was for Republicans to send Palin in there.
The boos started first, then were overwhelmed by the cheers.
