For YCDTOTV, it's just the first season but there's a good chunk of the original DD run on Paramount+; at least a couple hundred episodes. It's most if not all of the original 1986-1987 episodes and the same for the 1988 syndicated episodes.
I've done the same as Retro and kept DD on in the background, surprised I've been enjoying episodes of that and Nick Arcade on a loop. It's TV comfort food.
