Thanks! Makes sense. I'll leave them some feedback.

Unfortunately, I don't have a DVR account (yet!). I can only speak to the live broadcasts.

This could be caused by the way my audio chain is setup, but thought it was worth mentioning in case someone has suggestions for troubleshooting:

Device: HDHomeRun Flex 4K
Playback Device: Amazon Fire TV Stick 4K Max Gen 2
AVR: Denon AVR-S740H
Firmware: Latest
Software: Latest
Behavior: Audio drift ...

I'll reiterate that, for me, this functionality isn't high on my list of desired features. Now, if DRM was removed from some of the IP channels in my area that would change overnight.

I'll also echo what the previous posters suggested above - if there's a way to allow the user to opt-in I think ...

I think Nick mentioned this feature just missed making it into the last firmware update?

I know there is a lot going on at SD right now, so I will just reiterate that the ability to see these would be cool, but I'm honestly in no hurry to watch T2, or PBTV. In fact, I'd be more interested in FM ...

Still not sure what is going on, but this morning I'm able to successfully tune in 103.1 using a Gen 1 Amazon Fire TV Stick 4K. THe only other device I tried to use is a 2020 Google TV TCL TV, but there's some weird stuff going on with it. I think that is related more to the TV, as TCL hasn't ...

Those come up sometimes if you just it sit there a while. Something defintly is different all of the sudden.


Unfortunately that is not my experience. Once the No Video Data error comes up, that's all she wrote. Hopefully, whatever it is gets fixed soon. I'd like to watch SNF with the Atmos ...

This might be broadcast transmission related, but just in case...

The open broadcasts from Sinclair - 103.1 NBC and 133.1 CW. - indicate No Videa Data when trying to tune.

Here is a video of Config GUI when trying to tune the channel:

Does this look like a broadcast ...
