Based on my learning style, I decided I would probably get more out of the BBG materials purchased from Logos if I also purchased the 36 lecture set on DVD. I've gone through the first six lessons on Disc one, and on lesson six, there's a loud snap/pop sound at apx. 11:06 into the lesson, and at apx. 19:37-39 it happens again a couple of times AND the audio drops out briefly as well.
I don't know if this is a defect in my copy of the DVD or if it's a defect in the master that's used to make the copies. If anyone else has the set, would you mind checking your disc and let me know if it occurs on your copy?
