So as promised, I returned my newer X1 dvr (XG1v4-A, AX014ANM) and replaced it with a one of the older X1 boxes (ARRIS AX013ANM) that I had been using for a long time. So far, I have not experienced any of the slow responses experienced and discussed here. I HAVE still seen various behaviors that are different than this dvr model was delivering a few weeks ago (ongoing software revs.?) but so far, I am happy to have backed up one rev. I will let the forum know if I have any functional problems to contribute and I will be watching the comments to see when I might brave the newer XG1v4-A and try 4K video. Xfinity had also scheduled me for a tecnician visit (to test signal quality) but once my replacement box was up a running again, I canceled that tech visit. fwiw - I also had a long conversation with an Xfinity tech on the phone and he seemed to understand my issue. He looked up my reference to this forum as he "pushed" this issue up his internal technical tree. He said that resolution (attention to?) these things are typically "months" out, in the best of cases. So that reinforced my plan to retreat to older hardware for the time being. I't been nice to have an Xfinity store in town ... which makes it easy to wander in for replacement hardware. Good luck, ALL. Thanks for this discussion (can you image how much more frustrating this would be without it)? In the words of the dolphins - "Thanks for all the fish!"

Per @Cody21 - I also have Very slow response time on many functions. Here is a "new wrinkle" (hint?). I have been running on one of the older X1 boxes for a long time (ARRIS AX013ANM). There have been *NO* 'slow' behaviors as described in this thread. Today, I swapped in a NEW XG1v4-A (AX014ANM) and the slow behaviors have begun (it's worse on the base DVR, but also ~noticeable on the two satellite XiD-C boxes. It has nothing to do with the remote (I have both the older XR11 and the new XR15 paired to the same system). Nothing else has changed (same hardware, remotes & coaxes, same internet, same room/couch/etc). The new system started slow and is getting worse. I will go ahead and do the "refresh" dance, but I am not encouraged by all the frustration on this thread and NO USEFUL RESPONSES from COMCAST. I have not returned the old AX013ANM yet ... I might be "downgrading" ... I can live without 4K which seems to be the only attraction.
