Basic Operations (Recording)
overlap. For example, this can happen if you are set up to record shows on a daily or
weekly basis, and a special show comes on that you try to record during the same time
slot.
Shows with Same Starting Time
If the overlapping programs start at the same time, the VCR records in order that they
were programmed. If the shows are all scheduled to start at 7 AM, the VCR starts with
the first program at 7 AM, and switches to what remains of the second program when
the first program is done recording, and so on.
Shows with Different Starting Times
If the programs start at different times, the VCR records the show scheduled to start
earliest, records the entire show, then moves on to the show with the next earliest
starting time.
To avoid recording only bits and pieces of different overlapping shows, review your
programming and delete those shows that are not essential.
