Did you have to buy the Premiere through TiVo, and did you have to pay full MSRP (not the subsidized price they advertise)? The stories I've heard of people moving their grandfathered subs to a Premiere involved having to do both of the above. And there is this, a current screen shot of TiVo's service plan options for the current 2 tuner Premiere: OP, you just need to call TiVo and mention what I highlighted in the above screen shot. First, that you want a no commitment plan by telling him/her that you would be willing to pay full price for the Premiere, and then mention that you would like to move the sub from your TivoHD to that new Premiere. Don't take no for a first answer. Ask to be elevated to a supervisor. Be a squeaky wheel. Be firm, but be nice about it if you can.
