I bought the Roamio Plus today. Everything went fine with installation, except for my existing expander which shows as "unsupported" in my Roamio.
It is the same expander (approved by Tivo) that I have been using with my Premiere 4. I made sure I unpaired it from my P4 prior to hooking it up to my Roamio. Roamio recognizes it on the pop up screen, however, it shows it as "unsupported" when I try to set it up.
I called Tivo and they could not figure it out. They said it may be a problem with the hard drive, which I doubt it since it was working great until I got the Roamio.
Any idea on how to fix this?
