I'd even go so far as to say it's a superior experience because you can speed up the filler, rewind when something is unclear or when new information give a different context, and pause while looking up something up. And you can still ask questions asynchronously (so there isn't a time pressure for the teacher to answer something quickly) in the comments, with a precise timestamp instead of relying on human memory of what has been said; other students can even answer too. In-person university lectures are the only time I experienced boredom because it felt like such an inefficient way to learn things.
