TV At Bedtime?

My wife and I have a reoccurring disagreement. One that just won't go away. I cannot STAND the TV being on at bedtime. She likes to fall asleep with it on.  She also has no problem with the TV being on for the kids, which is a pretty big no no to me.

Just wondering if any other couples have had this disagreement? Have you come up with any workable solutions to resolve it? HELP!!
