111 This can be used to adjust the minimum FCK/PCK ratio.
112
113 With this you can make sure that DISPC FCK is at least
114 n x PCK. Video plane scaling requires higher FCK than
115 normally.
116
117 If this is set to 0, there's no extra constraint on the
118 DISPC FCK. However, the FCK will at minimum be
119 2xPCK (if active matrix) or 3xPCK (if passive matrix).
