Well, I had this problem with the Premiere XL and today, after about 2 weeks of use, the Roamio Pro is not responding to either my universal remote, the Tivo remote with IR or RF or the Tivo app remote on my iPhone. I get the yellow flash on the front of the unit with the remotes (not the app), but the Roamio just sits there acting dumb. I cannot pause or get to any menu. Great! I guess I'll yank the plug to get a reboot. I hate doing that as the aforementioned XL hard drive died when I was replacing it with the Roamio. Thank goodness for Weaknees.
