It could be. If you are using the app at home you should log out of remote DVR.
I am not in remote DVR…I have my HDHR AND my ATV direct to my router so I KNOW its not my network. I’m getting great speeds…EVERYTHING else on my network works…I don’t understand what is going wrong. I can use the app from my computer as well as the app from my cell and it works just fine. I’m at a lost for words what is causing my issue.
Plug the DVR in too.
what do you mean?
Plug dvr into switch/router with ethernet, then test it again.
My DVR is a Mac Mini and it is/has been plugged into a switch. This set up has been working perfectly for years and then today it just stopped. I can watch perfectly fine with the HDHR view app. some tvs work on 5Ghz wifi but if its wired then its a wrap its NOT working!
Sounds like this is the only thing that changed recently? What kind of router is it?
Try visiting my.hdhomerun.com and click into your prime, then into tuner status. Check to see what the signal quality and streaming rate are when watching from a tv that works and from a tv that doesn’t work.
On the Apple TV that’s not working, try the free app InstaTV and see if it has the same problem.
Thanks for the reply. I have since rolled back the update and my signal strength and quality are at 100%. Channels (and InstaTV Pro) are working on several other TVs but the main one in question it stutters in BOTH apps.
What about the streaming rate to working tv vs stuttering tv. I would guess the rate is significantly lower.
None of the Tv’s are working 100% flawlessly. Eventually they all start messing up some more than others. how can I check the streaming rate of each tv?
This probably has nothing to do with your issue - however, I have noticed that when I turn on my plasma TV (which is about 12 feet from my antenna, albeit through a floor/ceiling), my signal strength / quality degrades significantly. I have a strong enough signal that it doesn’t cause problems - but if I was on the edge of having sufficient signal strength/quality, it could easily push me over the edge.
Of course, if you’re not using a plasma TV, never mind! 
But if you’ve physically moved anything since it was last working well, interference could be part of it…
I have led Tv’s & im using a HDHomeRun prime with a Comcast cable card.
The Best TV (rarely stutters) has 98% Quality and 4.169 Mbps Streaming Rate
The Other TV (sporadically stutters) has 96% Quality and 2.421 Mbps Streaming Rate
The worse TV (stutters often) has 100% Quality and 0.358 Mbps Streaming Rate.
what can cause such a difference in Streaming Rates?
just want to make sure you know that I am attempting to look at channels on site with an ATV running TvOS11
The streaming rate indicates how much data the tuner is able to send to the client. If you’re getting good quality at 4mbps, your Comcast channels must be h264. For local stations the rate will be higher, 12mbps or more.
Since your other Apple TVs are dropping half or more of packets, it explains why you see stuttering. This happens when the network isn’t working properly.
Do you have more than one router/switch? How is everything wired together?
You could also email [email protected] to see if they can gather more diagnostics from the hdhomerun side.
ok thanks a lot…I would have to check to see if I have another router. My old set up was modem >> Airport Router >> Gigabit switch >> devices but my switch went out so it just became modem >> airport router >> devices.
are you telling me that it is a network issue and not a channels issue? Cause all of the other devices work fine.
If InstaTV has the same problem then it’s not a problem with Channels.
I had to retire my AirPort Extreme recently too because it started having lots of problems.
its frustrating because I use the back to my mac component a lot. Do you know of any tests I can run to see if its the router besides just replacing it?
Probably easier to pick up a simple gigabit switch and plug everything into that. That way the Apple TVs and HDHR can talk to each other and the router doesn’t need to be involved since it’s all local and not going to the internet. You can find a 4-port on Amazon for under $10
