That too, that too... but I'm starting to wonder if they're pressuring them to cut certain shows first to drive up DVD sales. Here's the logic behind my reasoning... the exact opposite happened to the 90's Saban produced Spider-Man series on Toon Disney. Since Disney owned the show (this is before they bought Marvel, but well after they bought Fox Family, which put them in control of Saban's shows). They adamantly refused to release the show on DVD, even though movies were coming out, so they would keep the ratings up. Marvel wasn't too happy about this, and there was a longstanding feud between the two until they were bought out.
Now, I'm sure the main reason why they have to shellac the old show reruns is to get the imaginary demographic (people who are happy watching everything else that they'll never get to watch them), and putting on dumb reality shows, out of place movies, and newer shows... but I'm starting to wonder about DVD sales as well...
