Recorded program pause and jump while watching and fast forwarding not working right

I got Cox TV in November when I moved.  I had Direct TV since 2005 and I am sorely tempted to switch back.  I have had nothing but trouble with my recorded programs.  I called and had tech support come out, nothing helped.  I went into the Cox store and they gave me two new boxes, helped somewhat, but still having problems.  Tonight while watching a program from Hallmark Movies and Mysteries, the program jumps, skips, and the sound goes away around the jumping.  Also while trying to fast forward through the commercials it skips forward a full minute, then when I try to go back, it goes back to the very commercial I started with. I have seen other issues that are similar with recorded programs all the way back 6 years on this forum.  Any idea what is going on with this?  Can it be fixed or do I just need to go back to Direct TV????  Getting very frustrated here.  I have a panoramic wifi and cloud recording.
