[GEM-dev] [pix_video] osx (fwd)

[chris clepper]

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.
