The History Channel puts on some very good documentaries, but unfortunately when they transfer them to DVD they don't do any re-editing. When these shows are originally aired on TV, there are commercial breaks of increasing frequency, and before every break there's a "peek" at what's coming up; after the break there's a recap of what's gone before. This is annoying enough WITH the commercials, but without it, one ends up watching the same footage over and over and over until it gets to the point of there being about two minutes' content per segment, bracketed by five minutes of recap and another five of "coming up!" I finally had to just turn this off as it was managing to bore me to death while, at the same time, driving me crazy (no small achievement if you think about it). This seems to be a pattern with History Channel DVDs, which is a pity because the program content is wonderful, but save your money and, if you want to see these messes, rent them from NetFlix.
