<P><B>Hint</B> : are the colors messed up? Then your tuner can't display
in YV12 colorspace. Try I420 (you must use the <CODE>-vc rawi420</CODE> option too!), or YUY2, UYVY, RGB32 (this one
with <CODE>-vo sdl</CODE>) colorspaces.
You can specify these with the <CODE>outfmt=YV12</CODE> option see below.</P>
