110 This can be used to adjust the minimum FCK/PCK ratio.
111
112 With this you can make sure that DISPC FCK is at least
113 n x PCK. Video plane scaling requires higher FCK than
114 normally.
115
116 If this is set to 0, there's no extra constraint on the
117 DISPC FCK. However, the FCK will at minimum be
118 2xPCK (if active matrix) or 3xPCK (if passive matrix).
