An interesting bit of trivia is that every day during the Vietnam War, the Department of Defense filmed all network news coverage by placing a motion picture camera in front of a TV tuned to each network and letting the film roll. The images saved are a little fuzzy, but are the only record we could find of what the folks back home saw during the battle. Several years ago, we tried to obtain the original footage from the networks, but it was lost - the National Archives contains the only complete record of this information.
It is easy to obtain access to the film - just go to the National Archives, register as a researcher (fill out a form) and head downstairs where the very helpful staff will get you set.
In terms of the battles at Lz Xray and Albany, the film is chilling. You get to hear Walter Cronkite, Chet Huntley and see a very young Peter Jennings (this had to be one of his first days as the ABC anchor) calmly talk about "human wave attacks" and "hand to hand combat". Actual battlefield network footage was shot on the Third Day of Xray when the press showed up to reinforce poor Joe Galloway. In the high tech world we live in today, it is interesting to see what low tech graphics passed for state-of-the-art back then.
