OK, just got new Roamio Plus with Lifetime. Removed from box, opened, and replaced stock 1 TB drive with 3 TB Seagate drive. Boot Tivo. It goes to the Getting program info screen, connects, configures, sets time, verifies account etc...but it won't get through "downloading program info." Says it was interrupted..check firewall, etc. I use both ethernet and wireless, even get rid of the router entirely and go direct connect to modem. Can never get the Tivo to set up. Frustrated, I gave up on the 3 TB Hard drive back and switched back to the 1 TB original. Tivo works perfectly and I get the initial setup easily finished. Should I try the 3 TB drive again now that I have completed setup? What's the difference between my 3 TB drive and the original 1 TB drive?
