TVE itself in Channels, is not going anywhere folks.
Though, it will probably forever be in "beta" status.
There are still plenty of networks that offer a TVE stream, whether or not those networks are offered by your streaming provider, and if they are of interest to you, is a different thing.
Years back, Channels DVR stood out to me for offering this, "TVE", as a source, to get most of the CATV channels, with a much cheaper Streaming provider like Philo. (and the other big streaming services that were much cheaper back then) I had never heard of TVE before i had discovered Channels DVR.
I was using Windows Media Center, then later on after i had to move away from Win 7, I switched to Emby, along with my Prime Cable Card tuner and Comcast cable tv service.
But, in traditional Comcastic! fashion, their frequent Price Hikes, finally got to me, when the same service i had had for over 30yrs, Cable TV service only, became over $230+ a month for the package level that had the 3 channels i mainly watched and wanted. It was a glorious day, ripping out the ugly, piece of crap cable box and cables, driving to the Xfinity store in my area, walking in, and dumping it all and say, "Cancel my service!" on Jan 8, 2020, after test driving Channels DVR and some Nvidia Shields for a couple months.
Now, 4yrs+ later, most streaming services are nearly just as much $$$ as cable/sat services, or you need so many, they add up and cost even more.
TVE may slowly decrease to just a handful of networks at some point in the future, but hopefully, it will last a few years longer and by that time, maybe there will be some other just as simple as TVE alternative to integrate those networks into Channels DVR.
