Actually, there are only four episodes that were cut from the Space Ghost DVD set. The reason they gave on the credits from last night's Adult Swim was because they didn't want to fork out the hideous amount of money that Jim Carrey wanted to put those episodes on disc (as well as a few other people). So, to fuck them over, CN is airing a marathon of those episodes in January....they also highly suggested any bootleggers to get prepared.
As for finding them, here you go:
Space Ghost Coast to Coast DVD.
Aqua Teen Hunger Force DVD.
There you go.
