Contour 1 has a 7 second "Skip back" button. I FF 6x through commercials and press "Play" then "Skip back" 2 or 3 times. I really don't like to sit through commercials. From the start of a normal length commercial to resume watching the program takes around 20 seconds. I think my thumb has developed muscle memory for that sequence of button pushes.
I did an Internet search for "contour 2 remote skip back" and found a May, 2019 post with the subject "Cox Cable Contour 2 - 30 second skip button Code" in another support forum. It showed how to program the page up button to skip 30 seconds forward and the page down button 15 seconds back.
Apparently Contour 2 doesn't have a skip back button like Contour 1 has, but it may be possible to program a remote to perform skip forward and skip back. Please note, this is just something I read and not something I've tried or know will work.
If somebody tries the reprogramming of their Contour 2 remote for the 30 second skip forward and 15 second skip back, please let us know your results.
