No. The 2-tuner Premiere models do not have MoCA capabilities, which is exactly why you need the adapter. In that situation, the MoCA signal enters the adapter from the connection to the wall outlet. The adapter converts that to Ethernet, and allows the Premiere to connect via its Ethernet port. To the Premiere, it has no idea what's at the other end of the Ethernet cable. For all it knows, the other end of the Ethernet cable is plugged directly into the router. All it cares is that it has a path to the router and can send/receive network info.
You should be able to stream shows between the two devices as currently setup. If you are having issues, force a connection to the TiVo service on each box, and then restart each box. Changes to network settings can cause issues in streaming between boxes. The restarts should take care of those quirks.
