Those are for if one of your units has HDMI connections but the unit your connecting it to has DVI. Like if you were connecting your dvd player to your receiver and your dvd player had HDMI connections but your receiver only had DVI, you'd use the HDMI/DVI cables.

Probably didn't explain that as well as I could of, if I didn't let me know and I'll try to better next time.
