Podcasts better than live lectures?

Students watching podcast of lecture did better on exam than students who attended the lecture in person. !!! Result could be because those watching podcast could pause whenever, take notes, reflect, etc. But note this was a very limited sample of 64 students for one lecture and one test. Still, it is thought provoking. Found while reading a blog re teaching sociology. Original study in Computers & Education, Volume 52, Issue 3, April 2009, Pages 617-62.
