I have nothing against instructors using the name of a military unit to sell either their own hand-to-hand combat system or one that is used effectively by that unit. Not at all. For the most part, I see this as a marketing thing and each instructor/author has to make decisions on that front.
If you want to connect a USB device to an HDMI device then you must use a converter box. This is a set of electronics that change the protocols and signals. The only adaptor which works is the DVI-HDMI ones.
Atlona's USB to HDMI adapter, also known as the HDPiX2, handles all of your audio and video, allowing you to simply connect a USB cable from an available port on your computer to the converter which in turn processes all the information and integrates the video and audio into a single HDMI line that goes into your TV.
