I'm pretty sure Gargoyles has been on Disney XD for a couple of years now. I remember waking up for some reason when in WDW last year, and I normally leave the TV on when I sleep so I can't hear my parents snoring in the other room. Anyway, I woke up and Gargoyles was on. Don't think I watched it though. Just tried to get back to sleep...
I'm really pissed that Disney suddenly took Lizzie McGuire off the schedule this month (in the UK btw), and replaced it with this awful Famous Five cartoon they made. I sent an email expressing my displeasure, and they sent one back saying it's not going to be on for the time being -_- We still have That's So Raven, Recess, and Kim Possible on though, so I guess that's good. There's also quite a few cartoons on Disney Cinemagic, but we don't get that channel as we have to pay more... I keep trying to get my parents to get it, saying I would pay for it, but they never do... Anyway, it shows Aladdin, Little Mermaid, Timon & Pumbaa, Lilo & Stitch, Dave the Barbarian, Lloyd in Space, 101 Dalmatians, Emperor's New School, Kim Possible, Recess, and Stitch (anime version of Lilo & Stitch). You guys probably still have some of those, but I'm not sure what ones...
You know what? I think Disney should copy what Teen Nick is currently doing. I believe the channel has a programming block called "The 90s Are All That" late at night, where 90s shows are played for 2 hours.
