Indeed. Did you have a theory about it being related to a specific EPG provider? Iām using Gracenote note on both Apple TVs.
What firmware version are you running? Can you try upgrading to the latest (20160630atest2) using https://www.silicondust.com/forum/viewtopic.php?f=119&t=20613
Hi
Iām using Version 20160328atest2, I havenāt been prompted to update.
The link you posted is from a post in June of last year, will that be the latest firmware?
Yes that links to the latest.
Does it matter that itās for the DVR?
The firmware is for the tuner. Updates are advised even if you donāt use SD DVR engine.
The latest Firmware Release should be 20160630atest2.
Go to my.hdhomerun.com in your browser and it should check your devices.
You will see something like this.

Okay, Iāve installed the latest firmware and Iāll report back soon.
Thanks
Unfortunately, Iām still having the intermittent picture hang. Itās most noticeable with sporting events (watching the Olympics atm), the picture pauses for a split second. Audio and video are still in sync.
As mentioned before, this doesnāt happen with other apps for the Apple TV (DVBlink, InstaTV to name a couple) and indeed on the Mac (EyeTV) too.
Iāve updated the HDHR to the latest firmware.
Really appreciate any help 
Can you try to catch a video of this happening? How often do you see it?
Yeah Iāll grab one later, although I did capture a video before and the issue is harder to see (I guess differing refresh rates from the iPhone and TV broadcast). I see it every 20 seconds or so.
Does it happen on both HD and SD channels?
Never mind you already said it happens on both.
Let me try to make some changes in the beta this week to see if it helps.
Thank you, really appreciate that 
Hi
Iāve just emailed you (to [email protected]) a clip with the subject āRE: Picture Jerkiness (from forum)ā.
Thanks
This should be fixed as of the latest beta.
Like I said in my email, itās looking good!!
Does this mean that I can use the Favourites pull-down menu now, and add more favourites?
Thanks
Yes, please use the app as normal now and report any problems.
Excellent. Thanks again for your continued and unrelenting support!
