Feel free to post corrections to the list or your favourite NAM video title(s). It would be great to have this grow a long list of NAM tv/movie/video material.
Here we go.
Platoon

Movie. Its pretty well known and good NAM movie. imdb link here
Full Metal Jacket

Hardcore NAM movie, starts from USMC boot camp and goes to Vietnam from there. imdb link here
Tour of Duty

TV series from 1987, amazingly good to give that dirty jungle NAM feeling. Three seasons, total of 58 episodes. imdb link here
Apocalypse Now

Old movie, quite good, kind of sicko movie but still good NAM stuff. In this movie they say that well knows "I love the smell of napalm in the morning.". imdb link here
We Were Soldiers

New pure Vietnam fighting movie, can relate to OFP VTE greatly because the fighting is the historical Ia Drang valley Landing Zone X-Ray combat. As this is new movie, you get excellent DTS sounds and picture quality. Very enjoyable movie with good compat scenes and lots of it. imdb link here
Good Morning, Vietnam

Famous Robin Williams more or less comedy movie from the war. The legendary shout "goood moooorning Vietnaaaam!" should be familiar with everyone.
imdb link here
Casualties of War

A bit sentimental girlie movie in my taste, ie too much crybaby shit. But still, a NAM movie and thats what were listing here. imdb link here
Dear America: Letters Home from Vietnam

Documentary kind of, real war footage. imdb link here
Hearts and Minds

Documentary sob story. imdb link here
Secrets of War, Vietnam: Alpha Strike
Somewhat "macho clishe" stuff in my taste, but still has real war footage. Has interview with that Randy Cunningham about when he downed a North Vietnamese MiG plane.
Hamburger Hill

I have personally seen this movie when I was like 12, dont much remember except it has alot of combat in it. imdb link here
