I just have audio CD. He discussed his theory about King Tut in the course - it’s reasonable, although it can’t be proved.
The video version has a ton of really interesting photos. I usually just get audio versions of courses but a few are worth investing in video. The digital download versions are fairly economical and they keep records of your purchase in case you accidentally delete a course. As a pathologist (albeit not of the forensic variety) I found his detailed description of Tut’s possible murder in the book very interesting, although not everyone is convinced it actually was homicide.
I should add that the digital download is audio only. BTW, I’ve gotten a few Art History courses which are, of course, video only. Terrific stuff, as is Alex Fillipenko’s (sp?) Astronomy course. That one is fascinating although exhausting. 96 lectures, I’m somewhere in the 70’s now.
