gabucino 3b8074ebf5 From: Kir Kostuchenko <kir@users.sourceforge.net>
Hi, I found that command line options brightness, hue, contrast and
saturation does not works, becouse mplayer apply it, before open tv
(kernel says invalid ioctl). Here are simple fix. Please apply.

This is the correct patch, sorry for the confusion.
