More than ONE XG1-V4 Box

@XfinityEricB​  Would changing the box settings so it isn't recording on all boxes possibly help?

I have Comcast CABLE TV service only, our community of 1800 single family homes changed over to AT&T and all residents get their internet 1Gig service as part of our HOA fees.  (Upgrades to 5Gig are available.)  I kept the cable service, so internet driven boxes won't work.  There have been 4 tech visits since July and Saturday is visit number 5!!

@Tek​ Actually, one of the tech visits, they said I had great signal and removed the amp.

Unfortunately, no.  They ran a new coax from the podium in the street up and over my house to the connection on the other side.  That is only temporary and will get buried in the next week or two.  However, what I did notice (again, at first blush) is that a program (college football on ABC this afternoon) played fine when watching live, but if you went back to play something again (from the DVR) it had crazy and regular pixelation.  I haven't confirmed all the elements of this problem, since the tech was here this morning, but is it possible it is solely a DVR based issue?  (Also see my added post above about "Recorded on All Devices."
