Is anyone having issues hooking up a 2nd mini to a Roamio Plus. I keep getting a V70 error and cannot complete the Guided Setup. Only option i have is to Retry or unplug the power cord and go thru the setup again. I've read some of the other threads here and have tried just about everything that has been suggested except setting up Moca. I've rebooted everything multiple times, renamed Roamio and forced connections. The 1st mini purchased thru Amazon worked right out of the box. No issues there except for using the Trendnet 8 port greenNet switch as posted in another thread. Then I purchased a 2nd mini from Best Buy (open box one). After contacting Tivo, they determined it was a defective unit. So returned it and got a new one from Best Buy yesterday. Called Tivo to transfer the service to the new mini. And again after multiple rebooting, renaming, forced connections, I'm still getting the same v70 error. I'll need to call Tivo again to escalate this issue. It seems very unlikely that I would have 2 defective units in a row.
