Five will get you ten that if you put a load on it, the voltage will drop to nothing.
Is your meter set for AC or DC voltage?
While the video discusses the center conductor voltage, what is the voltage reading on the shield (it should be earthed before it comes in the house)?
The dish gets its power from the Hopper or a DPP44 so if the cable isn't connected to the Hopper or a DPP44, there's no power source (actually, I don't think the DPP44 inserter will send power downstream but if it did, it would only be <=28VDC).
