A number of shows are extending into the next time slot by a minute or two which causes a conflict when follow on show are schedule to record. Since the DVR allows the extension of record times, also allow the shortening of record times to avoid the conflict. Maybe just allow a choice to end on the hour or half hour.
I have used the manual record to overcome some of these conflicts, but there is no way to identify the show being recorded. I noted another suggestion to be able to name a manual record which would also help.
