It seems that we can't support Windows XP anymore.
We changed the compiler of Bandicam and the new compiler has a compatibility issue with Windows XP.
Please use Bandicam 2.3.1 for Windows XP.
(We will send Bandicam 2.3.1 to your email address.)
Sadly, none of that worked.You could try some different combinations, like thr MPEG-1 codec in Audio and Video,
scaling down your screen resolution or
try to record something in DirectX / OpenGL mode.
