Kind of pointless to have a DVR if anyone can gain access to it that's the critical flaw here. There is all kinds of things he could of done to it. He could of had prior knowledge of the type of DVR before executing the plan. Since it has USB ports and DVD tray access he could maybe flash the bios, or destroy the heads on the dvd simply putting some drops of oil or acid on the cd surface and let it spin up. Maybe he factory reset the DVR? Some have codes and pinholes to reset them just like a router can. With prior knowledge you could plan such attack. Once the password is reset that can ultimately lead to formatting the disc clean. Also, many of these devices have grills on the sides for air flow, you can jam a long thin piece of metal in there and do all kinds of damage to the surface components of the motherboard. As others have said, slamming it down and getting the drive to fail that way and corrupting the data.
