They must be sure to have the red button functionality by then then as that was the initial sweetner with the free multiroom when people signed up for Tivo.
They let you move the V+ to another room for free so you could continue to use the red button/reminders etc as they had so much flak that Tivo did not have that functionality.
It's the only thing that has stopped me from changing my VIP50 V+ to a Tivo but it sounds like my best option is to let it die of natural causes.
