Hey patty sorry your having problems we have a Help Topic just for 3D problems so everyone can go to one place and not have to hunt through random posts.viewtopic.php?f=24&t=72260
New movies are being added in plain 2D format there are also a lot of 3D movies.
You don't have to watch 3D if you don't want to if a movie that you want to watch has no 2D sources then make a request in the Request Section, or Like Gspat said you can change the settings and still watch it.
It is blurry because it is 3D you have to have glasses and the player set correctly which sounds as you did. These are not plain movies they are encoded with two pictures and this makes the 3D affect/blurry.
