on top of that, the last F on the screen settings means the channel is actually Free. the same happened to me after watching tv for a while on my CS 8100 and still I have no idea why. After powering off for a while I power it back on and it started working perfectly. this machines are computers and like any computer the live by the murfy's law , they sometimes do not work as intended for no apparent reason at all.
BTW, When the installer finished , where all the channels scrambled?, Or you scanned them in later by yourself?. Any how it seems to be software related, you could power down and wait or you could re-flash the factory sofware and see what happens.
