How do I change the names of devices on an actiontec gt784wn

SOURCE: Actiontec GT701-WG doesn't recognize a DVR on the LAN

I think the screen you may be looking at is the Application layer forwarding screen, the drop down box being populated by DHCP clients, that's why it isn't seeing the DVR. The DMZ Hosting screen doesn't have a drop down box, it only requires an IP address to be entered.

Hope this helps!
