Thanks, guys! I was hoping that was the case. The fact that it can't stream from my older TiVos isn't a problem, as I'm planning on selling all three of them and getting some Minis instead. I'm probably going to be selling one of my 2-tuner Premieres as well. With the addition of the 6-tuner Roamio with such a large hard drive, I'm sure I can make do with just the Romio, two Premieres, and 2 Minis.
