Xfinity recordings start 1 min early and end shows 1 minute early

All of my recordings start a minute early but then cut off about a minute at the end. This happens on all channels and seems consistent. And all the Times when you have the option for the quick forward over commercials. It's off by a minute as well very annoying. 

I've heard everyone complaining, but the only very partial solution I've seen from Comcast is to set your DVR to record 5 extra minutes.  That is not reasonable and creates a conflict when recording back to back shows

COMCAST DO YOU HAVE A REAL FIX?
