How to edit the scheduled stop time on a recording with negative minutes to resolve conflicts (1 Viewer)

[OTA Watcher]

I get a conflict every time a TV show claims that it stops one minute past the hour. That causes a conflict with the next hour since the one minute overage claims the entire next half hour or hour as if it was a continuing recording. Is there any way to edit the stop time so I just lose that one minute? ( like my old VCR let me do where I could manually set the start and stop time.) Obviously they do this to mess with DVR recordings. I edited my TV server post processing stop time to zero extra minutes and that did not help because the exact stop time is still one minute into the next hour. Maybe allow for some minus minutes in the TV server recording post processing stop time configuration tab? Say at least up to three to allow for them to add more than a minute to a program? Also have it apply to just the new recording by allowing editing of the start and stop time when a conflict arises instead of only being able to cancel the recording. I have an HD Homerun with 2 tuners. I cannot add a third tuner because it overloads the computer and pixellates every program being recorded, but that is another issue and not for this question. I just mention it because I already tried that and that is not a solution for me.
