i have little bit different O.O
macro ON, night OFF -> no problems when switching to video mode.
macro ON, night ON -> phone restarts when switching to video mode :)
very ugly bug
but still.... gd driver (Y)
PS: i got into video mode (macro ON and night ON), everything was ok, i went out of camera to standby and entered camera again. camera was still in video mode (macro ON and night ON) and phone restarted. after reboot i went again into camera and again restart :D, few times more and i managed somehow to get out of video mode :p
