DirecTV over Internet with Genie HR54-500 DVR?

I would like to get DirecTV over Internet (because I don't want to have a satellite) but I want to be able to use my Genie DVR.  Is that possible?  I haven't been able to find any wiring diagrams showing how to set that up.  I currently have spectrum cable at 100 MBPS and have ethernet runs to all TV locations from my router, as well as Unifi access points throughout the house for very strong WiFi.

Second question, I am finding very different answers regarding the DirecTV over Internet cloud DVR.  Can you pause live TV with it?  if so, for how long?  If the cloud DVR as close to performance of the Genie, maybe that will be good enough.

Thanks very much
