This is a comparison between the censored NBC broadcast (TV-14 LV) from the 24th of November 2012 at 20:00 (8:00 pm) EST and the uncensored US-DVD.
It was changed 1 time in a visual sense (zoomed in picture to not show burning people) and 2 times in the audio track with no time difference.
The Indiana Jones movies always had the feeling of an archaeological James Bond. The "pre-credits" sequence was usually about something that was not (or just barely) related to the plot of the actual movie. In "Raiders of the lost ark" it was the idol and an encounter with Belloch; in "The Temple of Doom" it was an encounter with Lao while Willie was present; in "The Last Crusade" it was Indy's long hunt for the Cross of Coronado, which belongs in a museum, and his relationship with his father. The fourth movie directly started with the name giving crystal skull and a minimal setup.
There were other missteps that were mostly George Lucas' idea, who made it clear with the Star Wars prequels that he shouldn't do movies unfiltered anymore. But contrary to other sequels of older movies (e.g. Live Free or Die Hard) it feeled like a new adventure of an old hero, and this is the reason why some missteps can be forgiven more in this movie than in others (e.g. Live Free or Die Hard).
The picture was zoomed in to fit the (wide)screen, as the movie wasn't filmed in the 16:9 widescreen format, but the displayed text was still the same height. As usual for zoomed in US-TV airings, it wasn't zoomed central all the time. It sometimes showed more from one or the other side, which created some new pan shots e.g. when a person tried to move out of the visible screen area.
The NBC broadcast shows information about the changes before the movie starts.
The NBC broadcast is zoomed in as the Russians get burned, not showing any of it.
Mutt says "Bull spit!" instead of "Bullshit!"
Mutt says "Oh, shoot." instead of "Oh, shit."
NBC only shows the first credit entry during the closing shot, namely the ILM Animation Supervisor. It perhaps was meant to be removed but forgotten. Both versions then fade to black, but only the DVD-Version shows the entire credits sequence. The NBC broadcast shows scenes from an upcoming episode of "The Biggest Loser" while the credits get shown differently beneath it - and much much faster.
