Dxtory Not Recording All the Screen

[Vliq]

I'm using Dxtory for Minecraft, and it only records the full screen whenever I go into full screen mode. (F11)
Whenever I go into the fullscreen mode the chat gets way to big, and that's why I like the screen to just be maximized not full screen. I'm pretty sure it has something to do with the size setting in movie settings. I have it on 1366 width and 768 height. Help please.
