I haven't listened to his Old Testament series yet, only most of the second. He makes no claim as to which versions correct or better than others, simply lays out what they say, where they came from, who was responsible for them etc. The first series looks interesting, looking forward to it. I'm sure there is plenty of nonsense theories and claims floating around out there, I'm really only interested in hearing what the claims are and what the evidence is to back it up. From what I've heard from this fellow so far, he really only seems interested in the history and archeology of the Bible, not really proving that one view is the correct one.
