The movie "Prom" question.....?

First of all I wanted to see if the movie "Prom" was out on D.V.D yet?
Also, is the movie "Prom" on Comcast on Demand? Because I have Comcast
on Demand and I wanna see that movie very bad. My parents and sisters
aren't interested in those kinds of movies so I can't watch it at the
movie theathre. I was going to invite my friend to watch it with me,
but she didn't seem like she wanted to watch it.
