Many video capture devices have multiple physical inputs and some manufacturers use and input to set things like PAL/NTSC or colorspace or even resolution. The only way to really figure it out is with the 'dialog' window. It is kind of a pain to configure certain devices and some of the pix_videoDarwin code contains workarounds so I could do plug and play installations all over the world.
I thought I added this to a help file long ago in a Mac specific subpatch. Maybe not.
