I just purchased a Roamio OTA directly from Tivo, and am shocked that I cannot get it to show me the previous 30 minutes of whatever channel it was tuned to before it was put into standby. My Premiere, which is what I’m “upgrading” from always has 30 minutes waiting on both tuned channels. I have made 4 calls to Tivo tech support, and 3 out of 4 techs said “just do this”, call back if it doesn’t work. It never did. 4th tech told me it’s not something that any Tivo can do, including Premiere. Any Roamio owners who have had any luck?
