"Roamio is doing something that is using all tuners" error

For those who get this "All tuners are in use" error when in fact they are not (not even close), the prime suspect is the Tuning Adapter.

I had mine go stupid a couple of nights ago (not unsync from Mom, just lose its little mind), and none of the Minis would work for more than a minute before throwing up that message, not even when tuned to channels that didn't need the TA to work.

Rebooting the TA fixed the issue, although it did take the thing more than an hour and several reboots before it synced. I was able to use both the Roamio Plus and the Minis while it was struggling to reconnect to Mom.

I hate Tuning Adapters.
