I apologize. That's probably my fault. I have more than one DVR and I must have mixed up the the two. Although they are both experiencing the same problem.
In an effort to resolve this, I considered that maybe DVR has an old password cached and isn't using the one I enter. I've changed Hulu's password ten times in the last day or so. I keep a record of my old passwords in my password manager, so I changed Hulu's password to some of the old ones that worked back in 08/2023 (this all used to work!) and I retried adding Hulu as a TVE source without success. So I feel I can dismiss this as a possible problem.
I had Hulu on the phone for two hours yesterday, and they've escalated my case and suggest they'll respond within 72 hours. I can surmise that I am alone in this problem, and that this isn't a systemic problem with Channels DVR.
But I can promise that I'm changing the password, verifying it by logging into Hulu with my browser, and using the username/same password when I try to add Hulu as a TVE source.
