I would like to set the shutter speed when using continuous shot mode. The only place I can see to set a shutter speed is in single shot overrides, but that doesn't seem to change anything.
In CHDK, overrides should apply to both continuous and single shot. If you want to change the shutter speed during a continuous shooting sequence, that can be done using CHDK 1.3
One concern is that auto white balance is on. I'm not sure if that makes a difference or not.
It should not affect shutter speed overrides.
btw I have ver 1.86
That sounds like an SDM version, so it may not behave the same as CHDK>
