I've got them.
They're the re-edited movies. No old Indy whatsoever.
I'm not done watching the entire set yet, (it's really long) but so far the quality is excellent, better than probably ever aired. The documentaries are pretty good. And long. Like really long. The one on T.E. Lawrence was 35 minutes, and it was one documentary of four on that disc.
I got it for 69 dollars on sale. Regular it's 99. I'd have rather seen a set more like the movies had. Full length documentaries on the MAKING of the show, not just the background history. Audio commentary, etc.
And I'd rather have the episodes, not the movies, but it's still worth it I think.
