It's interestng that you should say that, because the reason I don't usually like lecture videos is that they're too fast to keep up with, especially if you're writing notes. The worst thing is a guy talking and clicking through slides both at the same time, and we're talking about slides with equations the like, things that really have to be read and thought about.

Then again, I don't like real-life lectures much either, unless I've already read the associated text for that lecture beforehand.

I wonder if people like lectures for the same reason that people like brainstorming, group work, etc, which is that it might feel like you're getting more work done than you actually are.
