I’ve experienced both, and I am favoring the video CDs because the format is better.
1. You can start studying now - don’t need to wait for class to start.
2. Doug spends too much time answering questions in the online class. You have to sit through people’s stupid questions. Thus, less time spent on lecture.
3. Video CDs allow you to rewind and play.
4. You get the slides in a book format for the video CDs.
My 2 cents.
