xvidtune needs to be updated to support xrandr before it will allow
you to chose which crtc to adjust.  That said, it won't affect tv-out
anyway do to the way it works and is implemented.  You can control
various tv-out options via xrandr (xrandr --verbose):
        tv_vertical_position: 0 (0x00000000) range:  (-5,5)
        tv_horizontal_position: 0 (0x00000000) range:  (-5,5)
        tv_horizontal_size: 0 (0x00000000) range:  (-5,5)

e.g.,
xrandr --output S-video --set tv_horizontal_position -2
