I've purchased a new TiVo mini from Amazon for my granddaughter. She spends most of her time at my son's home, where he has a Roamio Plus and mini of his own. I'd like to determine which account is the best choice for activation of the new mini -- mine or his. Are there issues with moving a mini between homes/accounts? In particular, if I activate it here at home and on my TiVo account before I wrap it up for her, will it have difficulties accessing his Roamio Plus to get a tuner or watch recordings? Thanks for sharing your experience and expertise!
