Haven't seen posts yet related to Dynamic Tuner Allocation (DTA) when using Roamio as a Mini host. From my recent experiment here's one interesting find: * I setup my Roamio Plus unit as my Mini host, and set it to record 5 shows concurrently with the last tuner as live TV foreground tuner. * Then I tried live TV on Mini and found it could not grab a tuner which was a little unexpected. So it looks like the Roamio reserves 1 tuner for live TV on the Roamio itself which the Mini doesn't automatically steal. Makes sense after you think about it a little. * On Roamio I then set 1 of 5 ongoing recordings as the foreground tuner. * Trying live TV on the Mini then worked - reasoning being that since live TV was no longer in foreground that there is no reason for TiVo to deny that tuner for the Mini anymore. So, under normal conditions where you don't have access to the host unit to change foreground tuner, the Mini will need 2 free tuners on the host in order for live TV to work. I don't think that's immediately obvious to unseasoned Mini users. Of course there are plenty of other experiments to try which I haven't bothered with, but figured we can probably collectively try all scenarios and perhaps after posting about the various scenarios, put together a FAQ on DTA.
