Purchased a retail Mini a few days ago and a few months ago purchased my 3rd TP-4 (retail when the price was $199). I activated both with Lifetime a few days ago. The Mini and the new TP-4 set up great, could see all my Series 4 TiVos and use MRS on all of them. Set up the new TP-4 for the Mini to use one tuner. Set up my Mini and the new TP-4 had the red circle death, I could not select that unit, the other two TP-4s could be selected without problems. I have tried everything, re-booting the new TP-4, re-booting the Mini, even did a C&D all on the Mini, I can't select the new TP-4, I even tried disconnecting one of my older TP-4s, still had the circle of death on the new TP-4. I give up, I did call TiVo and they could not see any reason for this problem on their side, will be escalated to engineering. My plan was to sell my other two Series 4s with 2 tuners, so I would be left with 3 TP-4 giving me 11 tuners (and one for the mini) and one Mini, more than enough for my home. Any help would be appreciated.
