Hi E.,
I don't know of any parent who hasn't used the tv as a "babysitter" at some point. There are some great educational shows that help teach numbers, shapes and letters and other that teach values like manners and friendship, that can be benefical to your daughter. There's nothing wrong with allowing her to watch these types of shows for an hour a day.
I would recommend doing a little research and finding out what shows are on at what times, and then setting up a tv schedule (one that works best for you, when you need sometime to focus). Remind her throughout the day, "no you can watch tv now, but you can watch it after lunch". You may want to use the tv or movies as a reward system.
I would save movies for special times or occassions or maybe just once or twice a week.
