Maybe all is not lost! I can think of two ways to get your shows from the deactivated box to your new box. Both ways entail passing the shows through your computer.Not the answer I wanted but was what I expected, thank you.
Diane, I suspected that might be the case and that is why I offered the second solution, albeit at a cost of $75 (buy a $75 WinTV USB stick on Amazon (WinTV-HVR-950Q) and connect your old box to it). AV out from the old box into the HVR to a USB port on the computer. View the shows on the computer which will also record what is being viewed in an MP4 file (CP doesn't matter). Then pyTivo to the new (network connected) box.This is the flaw in your logic, a deactivated box will not have network capability for Tivo Desktop or other applications, a deactivated box will call in, set its clock, and download OS updates only, no transfers, no guide data, etc.
Where is that? Sadly, at $189 at Amazon.com, from Marketplace sellers (Amazon no longer itself selling it, seemingly).
Actually, the post is quite appropriate since someone who gets the upgrade offer must decide between getting the 3Tb Bolt+ or getting the 500Gb Bolt and upgrading it him or her self. That person would be quite interested in knowing the different HD choices.
