There is nothing in this entire DVD set that I have not seen elsewhere, so that knocks it down one star right there. The title of the DVD is flat-out untrue. In fact, I know many things about Hitler that this DVD missed.
The other star was lost because it is a very cheaply produced DVD. Some examples: the narrator over-pronounces his words, which gets tedious. It seems he's incapable of using any contractions, and it sounds like an android is telling the story. Also, he stubbornly mis-pronounces some words repeatedly, such as saying ROOS-evelt rather than the more commonly used ROSE-evelt. He incorrectly pronounces it exactly as it's spelled. A minor point, but an example of how annoying the narration is at times. The graphics are cheesy, as is the music. Ah, the music! Wildly inappropriate at times, such as romantic symphonic music or peppy jazz music while showing intense, violent combat footage. And, the sound effects were lacking at times too. While showing British ships launching anti-submarine hedgehogs, they used the sound from the Soviet Katyusha rockets, or "Stalin's Organ." And in another scene with combat troops going at it, I swear I heard a Wilhelm Scream in there. You can look it up on youtube if you don't know what that is.
This is a DVD that has definitely earned its place in the $5 bargain bin. If you can get it for $5 or less, you might as well, it's not completely awful. But there are much better WWII DVDs out there. I'm still waiting for the DVD release of "Rise and Fall of the Third Reich," if that ever comes out on DVD.
