If I am understanding correctly, there is no ‘penalty’ to the network connectivity, but for the 30 second overlap, the data will be saved twice, once for the preceding recording, and once for for the upcoming program. Small penalty I realize, but they add up over time.
I did prefer the original functionality prior to the modification for automatic pre and post roll however.
