1212	Invalid memory access with lead h263 and lowres	ami_stuff		"the crash happens after seeking a few times with the mouse

below log is from ffmpeg git-ed68fd4 (9 Apr 2012) - looks like enabling sdl outdev at the same time disables output to the console here (mingw)

(if it's libsdl's bug then maybe it's possible to workaround it somehow?)
