I played around with the menu yesterday, and found something I think worked on my DVR, time will tell. I deleted the timers that didn’t work, deleted any shows from the DVR that were the same as the timer, then redid the “Record All” option on the shows. As of this morning they all recorded. (My problem channel seemed to be Discovery Kids). If it comes up again, I’ll bite the bullet and call DirecTV.
I should say, it didn’t highlight or record multiple copies of shows, which it has been doing lately. (What I get for trying to coherently post, with my kids and puppy wrestling a foot away, LOL.)
