MRV and internet at the same time - DirecTV

I have a HR24 in the living room that I had directly connected via ethernet. After adding a H25 in the bedroom, I realized the direct ethernet connection was keeping MRV from working. I disconnected the ethernet, rebooted both receivers, and success.
Now, can I get internet back into the system with paying for a Cinema connection device? My thought is to insert a splitter on the coax leading to the HR24, with one connection going back into the HR24, and the other connected to an powered external DECA connected to an ethernet cable. Will this setup work without disrupting MRV?

This question, "MRV and internet at the same time," is about DirecTV channels, programming, equipment, and sports.
