That's correct, @scarng. This is the same message as shown in the first post.
Look at post #7 for an official answer from the devs.
Too bad for them too, I have canceled my PBS membership.
PBS is not a public company. DRM introduction should make it clear.
This is another reason to add LocalBTV. Many of the locations have their local PBS stations as part of the package. And since LocalBTV gets permission from the stations before adding them, it seems likely that they will continue to be available that way.
Access to my local PBS stream has returned this morning. My challenge, however, is that I am located within reception of two different PBS affiliates.
The streams likely have added geolocation as I can no longer receive the second PBS affiliate which I can receive using an OTA antenna but is technically outside of the local market DMA.
Seems the same here. I am in the Boston DMA, but I'm closer to the Providence transmitter. My Providence PBS has disappeared.
Yes. There are no problems playing the streams on the site. They are just DRM-encumbered, and therefore Channels does not decode them.
I don't know why no one reads the post. It was mentioned that PBS has now DRM'd their stream and that should end the conversation. but they keep asking why the stream works on the site but channels can't. Channels User better get prepared to loose all national networks via online streaming due to DRM.
Yeah, because PBS broadcasts copyrighted material 
@racameron
My laptop with High Sierra is apparently too old to play PBS. Time to switch ...
Hi Neighbor!
Yeah, Providence and Nashua are gone, but Boston continues to work. I wouldn't care except Providence and Boston are on super low VHF on the main signal, so I can't pick them up with the current antenna. TVE was my savior here. Subchannels are on UHF and work great, though!
I don't understand my pbs work in Sterium, so why not Channel Plus
DRM not supported. It's reported that DRM schemes were changed begining on Dec 1, 2021
While my local PBS stations through YouTube TV TVE are broken now, my custom channel for it still works (for now at least). If you can find the stream url for your station, you may be able to workaround this. This is my custom M3U for Louisiana Public Broadcasting:
#EXTM3U
#EXTINF:-1,channel-id="LPBDT" channel-number="27" tvg-id="27" tvg-logo="https://image.pbs.org/stations/wlpb-color-logo-a3yOPNj.png", LPB
https://wlpbdt.lls.pbs.org/out/v1/3f6379f418924ca39e09415a34c92738/index.m3u8
How did you find the stream url?
Back before the DRM, I was able to use the browser developer tools to snoop out the m3u8 file. Unfortunately, it looks like it's hidden behind the DRM now. 
There is a pretty good list here where you can pull out links for the station you want if it’s there.

Good point @sdust. And people that lost PBS through TVE, can add a "Custom Channels" source using that m3u url or copying out just the local ones that they want in as a text source with using local OTA guide data.
