We recently got a (base) Roamio and a Mini, and have had a Series2 for years. The Series2 has a whole bunch of recordings on it. The Roamio is the "home" server for the Mini.
On the Roamio, we can watch shows from the Series2, no problem.
However, on the Mini, when we try to watch shows from the Series2, we get a V120 error that says
The DVR you have selected is an older model TiVo DVR.
In order to watch shows on this DVR, you need to
connect to a Series4 or newer TiVo DVR. (V120)
Isn't a Roamio "series4 or newer"? Is this a case of the Mini not recognizing a Roamio properly?
