Yes. I see no issues in that menu, only when trying to play the channel. Error also appears in the DVR log.
So you clicked Rescan and it shows a checkmark? When you rescan it should reauthorize and fix the error that's happening..
Also doesn't make sense that Rescan would not show an error but playing the channel would, since rescan tries to play the channel as well..
How long should a rescan take? It appears to be almost instantaneous for me. I’m including a few screen grabs of the rescan and the error I’m seeing on playback... please let me know if I’m doing anything wrong...

Strange. The rescan should take 5-10s atleast. Sounds like there's some sort of bug, I will see if I can reproduce it.
Anyone have tricks for getting ATT U-verse TV to work? I get "encountered exception 'Uncaught' (5:5)" when adding the source. I'm using the latest beta, logging in with chrome browser, and read through the forums for any solutions. Or is U-verse just not supported? Philo and PS Vue work so well. I tried out a 5 day trial of PS Vue just to test this new feature. Its so awesome, I'm talking my brother into getting an HDhomerun with Channels DVR setup.
The last build works with my U-verse login. This rivals that cool factor feeling I had with my first TIVO about 19 years ago. Thanks for the hard work!
Noticed on a few (duplicate recordings (Cable+TVE)) the cable version was less susceptible to transmission artifacts than the TVE version.
I'm also getting the same anvato... error on NBC channels... MSNBC, CNBC, USA. Through Verizon Fios. I clicked the pencil and edit and rescan. Other channels are fine. When I go to watch through the websites, I get a chrome flash error until I enable flash for the page. Any ideas?
Did you update?
2019.07.19.0208 shows up to date for me. Good question.
Interesting I had the same issue, saw this and worked for me
The current version is 2019.07.20.0419
FiOS, and NGC is a part of my package, but NGC in TVE say's "notAuthorized".
Is this expected behavior?
Looking at https://www.nationalgeographic.com/tv/live/channel/NGC/
VZ FiOS is listed as apart of TVE. So are you updated? and have you done a manual re scan?
To follow up: Rescanning the individual channels with the most recent beta (2019.07.20.0419) fixed this issue. Thanks!!
Sure did; even removed the entire line up. I'm getting the same error with MOTORTREND
I can even log in using the link you provided with no problem.
@RJ_Make Have you tried rescanning the individual channels that are problematic vs. rescanning all of them? I found this option to work for me with the latest beta DVR for channels I was have authorization issues with using Philo.
Thanks and yes I've tried individual, and collective re-scan and even removed the entire line up. Results are the same.
Are iPads supported? I only get OTA
