How to Video Mirror to my Iphone Projector

Hello

I have bought the new iPad recently.

I have a projector for my Iphone 4s which i recieved as a gift

I also recieved a dokc extender wire that I used to connect my iPad to my Iphone projector. It is 30 pin on both ends and supports video out.

So far I can't do true video mirroring. I can use video-out functions (videos, photos, youtube, select Video/out apps), but I am looking to reproduce the entire screen via my projector.

Do i need to turn something on true video monitoring or is there a very specfic cable i am missing? I was kind of hoping this would work. Its nice to have some limited video out functionality but the mirroring function was one of my selling points.

I hope someone can help.

Also I am relatively new to the apple world...so don't be afraid to elaborate.

Thank you.
