How to save movies downloaded from ipad to laptop

[qak]

Greeting All,
I downloaded a movie from an app to my ipad3. Now I want to put that movie into my laptop so that I can watch it on the laptop. Note that the movie I downloaded is not from iTunes.
Thanks,
qak

I use the latest version of ifunbox to connect to the ipad 3. From there, i can browse the folders of the app i need to access. The movie should be somewhere there, stored in the main app folder or in a subfolder.
