Thanks a lot for your replies !
1) Exposure override wasn't enable. Enable it solve my first problem.
2) The shutter button was effectively sticky, surely because of the option "Shutter button : hold during REC" (I use to enable IS automaticly). But when this option is enable, after few tests, I note that I can stop recording after disengage the shutter button (by a full pression on it).
I also disable any shortcut on SET button.
However, I've an other question about ML : when I turn off my camera, my previous settings are lost. How can I conserve it ?
