I've came across some updated (I think) CNN Schedules for 3 of their 4 networks. Check out the following links below for a PDF version of the schedule.

CNN En Español
CNN/US
Headline News - A CNN Network

Keep in mind that these may or may not be updated, and current schedules can be found at CNN.com.... except for CNN/I their schedules on the site can't seem to be updated! (I won't even show you the printable schedule I found, it was out of date since like 2002!)
