New Movie Channels 1891-1894?

I'm seeing new HD channels right before the Starz block. Currently they say "No info", and a blue screen. They are 1891-1894. Any ideas? Glitch? EDIT: Ok, they were locked by parental controls -- I unlocked them and they were SD versions of Nick Toons, GSN, NBC Sports Network, and something else that escapes me. Weird.
