netflix stutter

I'm not sure my setup is 4k compatible with the 4k box despite having a 4k tv.  Not sure if my HDMI cable which is in the wall is 4k compatible and I also run optical cable from the tv to the soundbar so I'm thinking I'm not going to be able to watch 4k netflix through the new 4k box with my current setup.  Does the 4k box support regular HD just as well as the HD box?  

I tried resetting netflix multiple times on multiple boxes to no avail.  Getting a 4k box was the solution.

Yes, you can set the 4k box to output 1080 (and other resolutions).  They do make adapters to extract audio from HDMI but that sounds a bit like a Rube Goldberg kind of solution.  I would bet that Comcast can get this sorted out  on the none 4k boxes eventually.

I reset the Netflix app. It did make a difference- it is a lot better, but still not as smooth as 2 months ago.

Note: I have reset the app many times since the end of October- it never helped.

For some reason doing on Friday 12/4 showed improvement. I am hoping this problem will get remedied so it is as smooth as it was before the end of October.

Just discovered this thread after a Google search for Netflix Stutter.  I'm in New Jersey and have been having the same problem for several weeks.  Had techs out to the house 3 separate times, to no avail.  Moreover, none had heard of the problem.  Apparently, they don't check this forum or Comcast employees on this forum don't pass along the information where it could be disseminated properly.  The first tech swapped out my DVR box (the only one with the stutter), which left me worse off than before.  My DVR was 85% full or programming and, despite assurances it could all be retrieved from the cloud, only 5% came back.  I can't use a box without optical audio output due to my Sonos soundbar setup.  Took me three home visits to get a supervisor out as I requested, but he was of no help, either.  I've done all the usual troubleshooting steps, and the techs even replaced every cable and connection.  Very frustrating.

I sent a private message to ComcastMorgan but I figured I’d add my 2 cents here too. I’ve been having the same issue many of you have had - starting a couple months ago. I get video stutter with Netflix app on X1 DVR. The audio is fine but the video is not good and almost unwatchable. A month or so ago I refreshed the Netflix app and did a System Refresh and didn’t seem to make much of a difference. Lately the stutter seemed to be a bit better but still not good. No issues with Netflix on any other devices. I have no issues with Prime Video app through the X1.

I decided to refresh the Netflix app again today and did a System Refresh. When I went back to watch something on Netflix app the stutter was even worse - much worse. I then refreshed the Netflix app again and still the stutter is worse. So much for trying to make it better. FYI - I live in the Seattle area. This is definitely an Xfinity issue and sounds like I may need to get a 4K box to fix it.

One other thing I’ve noticed recently is if I play Netflix app (same thing with Prime Video app) on one of my remote boxes, when watching TV on my main X1 DVR box the video stutters (again no audio issues).

It does seem to stutter more when there is faster movement playing.

Hi everyone. If you're experiencing a problem with only the Netflix service via the app on an X1 DVR, it's recommended that you send me a private message including your name so I can check your premise signal strength, some other coding in our system, and open a request for tracking if it all comes back OK. 

Happening to me since about Thanksgiving. Only on DVR main box.

It doe not happen on my other box. Also, when other box is playing Netflix or on demand, live tv on the main box also stutters.

Hi @Bill2489, 

Thanks for letting us know you've been experiencing the stutter on Netflix as well. I can take a deeper look into your account to see if I can help find a cause. Can you please send me a private message with your first and last name?

I failed to mention in may earlier post that I am in the Atlanta area. I did schedule for a technician to come out to my house and he is supposed to have a new box. From what I have read, a 4k box seems to be the solution. So I will call so I am I right on just calling to have a 4k box sent to me and try that?
