You don't have the topic for anyone else?In that particular screenshot, I used the cheats to lower my knowledge down to 0 and worked it back up to 100 in order to see if I could 'proc' another skill gain to get the TV skill. It didn't work, however. I vaguely remember as I was levelling it to 100 the first time around seeing TV in there, I just happened to have left it for last, only now it won't let me pick it at all as I can't get the screen to pop up.
Cheat it to 100 and make sure you can't get it that way...
Then go through a day/sleep cycle... and try again
