I have noticed this problem lately. And, I know that I do not have 4 HD programs recording at the same time. I shouldn't be hitting that limit. I also have plenty of space available when this happens. I believe this is a problem with the firmware. Can someone from Comcast comment, please? Is this a known or new issue? Is it going to be investigated soon? Thanks!
Edit: I have the X1 DVR (Pace).
