The TiVo app for tablets has suddenly started offering "on time" as the only option for the end time when I use the app to schedule a recording.
The Roamio itself doesn't have this problem, just the TiVo app.
I have other recordings scheduled where the app did indeed once let me say "1 minute longer", but I can't do it anymore.
Could this be some kind of totally strange interaction with the new kitkat 4.4.2 update I got on my Nexus 7? It started happening at about the same time (of course, I also got the latest 20.3.8 update at about the same time as well).
