Yes, I have. I divorced my first wife and it was definitely not based on Biblical standards...in fact, I wasn't a Christian at the time. We weren't getting along and I left her...she wanted to reconcile, but I refused and proceeded with the divorce. It was purely pride and arrogance on my part (and immaturity and stupidity.) Later, I remarried, but before I accepted Christ. Am I living in adultery? I am, based on the Biblical definition, but I think I have been forgiven when I accepted Christ. My current wife was a Christian when we met, so she shouldn't have married me but she did. It was largely due to her influence that I became a Christian, so that was definitely a blessing for me. We've been married for 38 years now, and even though I should have remained married to my first wife based on Biblical standards, I give thanks every day for my wife now. [Interesting note: at one time, I was asked to be a deacon in the church we were attending; I said that I couldn't since I was not a man of one marriage. The committee said they didn't hold to that standard, because if they did they would have a hard time finding anyone! Sad commentary on our times. Still, I declined because I didn't feel that I could serve in that capacity.]
As for movies and television shows...there are obviously some that are unacceptable based on the content. In other cases, if you are watching an innocuous family show and find yourself lusting after the female lead, then that isn't a show you should watch based on your own weakness, which may not be a problem for another person. Even if your entertainment is innocuous but you spend time on it and have no time for Bible study or prayer, then it really isn't innocuous. (I am by no means saying that I am perfect in these issues...in fact, I fail daily.) It is a very difficult thing for a Christian today, with the unending barrage from every aspect of life.
