Oh, there are tons. Currently, though, I really only watch The Land Before Time and Peep and the Big Wide World (a very very cute sciencey show about a baby chicken, robin, and duck. It's really very intelligent and clever), the latter I found because I have a 3 month old sister and she adores it due to the bold colors XD
I occasionally watch Barney with her, too. She loves that ending song so I end up singing it all day...just like when I was a kid XD
I USED to watch Loonatics:Unleashed religiously but they've since taken it off the air =\
In my youth and if I ever happen to catch them on/dig them out of my stored collection (which doesn't have all of these unfortunately!):
Rocko's Modern Life, Hey Arnold!, Are You Afraid of the Dark?, Garfield and Friends, the Animaniacs, Freakazoid, Road Rovers, Captain Simian and the Space Monkeys (great series, anyone else catch it?), Street Sharks, Mega Man, The Adventures of Pete and Pete, Tiny Toon Adventures, Pinky & the Brain, Digimon (seasons 1-3), Pokemon (First 150 pokemon set, really), Sylvester and Tweety Mysteries, The Adventures of Sonic the Hedgehog (and the SATAM set), Rugrats (pre-Dil), the Powerpuff Girls, Foster's Home for Imaginary Friends, Donkey Kong Country
And like a billion other shows I haven't mentioned XD I hope I answered the question correctly. I pretty much just don't like the more modern stuff =\ Too anime-inspired and synthetic.
