While watching something for 10-60 minutes or so and I see something specific I want to record, I rewind to the point I want the recording to start and hit record.  I forward past the point where I want my recording to end and then stop recording.  More often than not, the recording captures the entire 10-60 I've been watching when all I want is 2-3 minutes of the show.  Conversely, when I'm watching something and want to save everything I just viewed and the rest of the show, I hit record and it picks up at the point I hit record.  It's like it knows what I want and chooses to do the opposite.
