Hmm... I wonder why they say 8? I know for a fact that the maximum number of devices allowed on an account is 10, so you should be able to have 9 Minis and 1 TiVo. I wonder if the Stream counts as a seperate device even when it's built into the Plus/Pro? If so then that would explain why they said 8. But in any case that doesn't apply to what I was saying. A single TiVo can only support 3 outgoing streams at a time. Or at least that's how many the Premieres support. It's possible the Roamio supports more, but given the limits of the hard drive being used I don't think it would be 8. The HDD they use supports 12 streams. There are always 6 recording, plus one playing on the TiVo itself. They also leave room for one incoming and one outgoing transfer. So that leaves 3 available for streaming. Now they may have changed the transfer thing to count as an outgoing stream, so it might do 4, but someone would have to test to verify. I have two iOS devices, a Mini and another TiVo. So when I get mine I'll try it out and see if I can max it out. If I can't all enlist my wife's two iOS devices and see if we can get 6 going all at once.
