Code to change skip back and forward

This is weird. I just received a XG1v4-p dvr. I did the exit exit exit 0030 to change the the quick rewind and forward from 5 minutes. It's supposed to be 15 seconds back with the down button and 30 seconds forward with the up button but it is just the opposite. Unlike on my last box, it's 30 seconds back and 15 seconds forward. That's not what you want.
