The only cartoons from my childhood I have on DVD are Transformers and the Macross portion of Robotech. I do have a best of Road Runner collection and that Best of Voltron 2 disc set too.
I am tempted to get Inspector Gadget and Count Duckula, and when there's finally a proper release of Sailormoon (either the dub or the original) I'll get them.
Extreme Dinosaurs never heard of that (and wikipedia tells me it's from 1997 so no wonder). It did make me think of Dinosaucers which was a show I liked as a kid and haven't seen in like 20 years. No DVDs of that show yet it seems, but that's an old cartoon I'd like to see again.
Usually though I find rewatching the shows I loved as a kid is a bit disappointing as an adult (Voltron for instance).
