A cropped, high-definition version of the series, with a 1.78 : 1 aspect ratio, is currently showing on the Universal HD cable channel. (All programs are shown in a widescreen format on Universal HD.) At the time "Hogan's Heroes" was originally shown, there was no such thing as widescreen TV, and all television shows were presented in a 1.33:1 "Academy ratio" format. "Hogan's Heroes" was filmed in this aspect ratio, not in the current HD 16:9 television ratio so popular today.
German broadcasts of the show differ from the original. For example, because Nazi symbolism had been outlawed in Germany, any time the German officers gave the Hitler salute and shouted, "Heil Hitler!", the German version dubbed in another, more bizarre line such as, "This is how high the cornflowers grow." Also, anytime the show alluded to actual bombing and killing, the dialog there was modified as well. For instance, when the Americans destroyed a munitions factory, the German version made it a toilet paper factory. And when Sgt. Schulz reported the Allies having bombed Hamburg, it was revised to the Royal Air Force dropping planeloads of candy as a "propaganda maneuver."
