iTunes University resources are pretty handy. If you have iTunes, you simply go to the iTunes search window and try to locate content. Now, there are also podcasts, but I tend to rely on the iTunes U resources, as I believe they are more properly vetted for accuracy. The links below are going to open up the iTunes program, and then go to the respective site. You will get a warning that this link is opening up the program.
I'm also compiling a list of links to South East Asian studies centers in the USA. It seems like there are a lot of them.
General Lectures and Vietnam War Centric materials
You can go to Columbia's University's lectures on the Vietnam War from the Vietnamese perspective.
