Hey M. - I'm willing to bet that this is just a phase. It's only been a week (I know, a week is a long time with no sleep) and many phases only last 2-3 weeks at a time. #1, letting her watch TV at this age isn't the greatest idea, but to let her do it in the middle of the night?!?!? That's basically rewarding her for waking up. #2, the rest of the house is going to have to deal with it, because you need to do what's best for your daughter. Everyone else is a grown up who knows how to put themselves back to sleep, right?!
My advice would be to go in when she wakes up and give her hugs and kisses, saying everything is okay and go back to sleep. Then leave. If she comes out again, or you hear her up and around, go back in, give hugs, say good night, leave. Next time go in with no words or hugs, lay her down, leave. (You will recognize this to be SuperNanny's strategy if you're familiar with her. It worked wonders for my daughter and my nephew.) If she's just screaming in bed, then leave her to do that. You only go in if she's up out of bed causing trouble or coming into your room.
I know it's hard to be calm in the middle of the night when you're sleep deprived and she's screaming, but that's the key to this working. She needs to see that you're in charge, you mean business, and she's not going to get her way.
Repeat to yourself, "It's only a phase. One night at a time." if that helps!! Many of us have been where you are, and have good sleepers now. You can do it!!!
