Disagree, and I doubt you're a regular user of YouTube TV given your comments. "The shows are limited" doesn't even make sense; you get access to the live feed of all the channels in question. The DVR works perfectly in my experience over the last year or so; it has never failed to record what I wanted it to record.
I use it every day. It's just now getting Comedy Central. I tried to DVR an episode of Atlanta and it just didn't do it. It did record an episode later on though.
