Bridging a network over the coax line

I have a DVR and a HD receiver with Whole Home service. The only problem is that my wife wants to redecorate and that will involve moving a server away from my router.

Now to the question: Both the DVR and the receiver have an unused ethernet port. Does anyone know if I can use these ports as a bridge to the MoCA network that is used for the whole home and also does anybody know of MoCA equipment that is compatible?

Thanks
