Okay. That works. Mostly. It does not work as well as just explicitly letting multiple devices share a tuner (by transparently hitting Record for the user). Reasons I say that: - If all tuners are busy and I want to watch something live from a Mini, I simply can't. Unless I just happen to know that one of the tuners is already tuned to what I want. And that tuner has explicitly intiated a Record. It would be EASIER for the user if, when you tried to tune something on a Mini and all tuners were already busy, it would inform the user that all tuners are busy, show the user what each tuner is doing, and give them the option to "attach" to one and start watching whatever that tuner is tuned to - regardless of if somebody else is watching it. That tuner is already recording to a 90-minute buffer, right? So at that point, I could even rewind up to 90 minutes, maybe, if I wanted. - if I'm recording something and watching it near-live, and all other tuners are busy, somebody else could start watching my recording from another TV and be watching near-live also, without my knowledge. If I then switch over to another channel, I'll have to stop my recording or one of the others that is happening. If I choose to stop mine, I will inadvertently kill the program for the other person that is watching. In contrast, if sharing was explicitly supported, when I try to change channels, the device could prompt me that another Tivo device is watching the same tuner and allow me to pick a different recording to cancel (i.e. I switch to another tuner, so the other watcher is unaffected), cancel the current recording but KNOWING that I'm killing another person's viewing too, or simply let me Cancel and stay on the current channel. In other words, it gives ME all the info I need and lets ME decide, instead of being locked out of certain choices. Sharing a tuner to watch live is not really any different than sharing a recorded program to watch on 2 devices simultaneously. Even live TV is recorded (just into a rolling buffer with a fixed length). So, the concerns about each one being to do its own pause/rewind/ff seems unfounded. The only issue I can see is controlling what the tuner is doing. And for that, I don't see why any Tivo device (Roamio or connected Mini) shouldn't be able to explicitly control the tuners. You're talking about people in the same house, right? If all the tuners are busy, and somebody wants to change one, why should it be locked to the device that tuned it? What's wrong with relying on Mom or Dad to check with the other people in the house to determine what tuner to change (if all the tuners are busy and they want to change one)? That seems better than having tuners locked to individual devices (to me).
