He,

bin nicht ganz sicher, aber versuchs mal so:

hr =  g_pd3dDevice->CreateOffscreenPlainSurface
(    
     infos.Width,
     infos.Height,
     infos.Format,
     D3DPOOL_SCRATCH,//D3DPOOL_DEFAULT,
     &g_Surface,
     NULL
);

Dazu würde ich Dir empfehlen, im DX Control Panel den Debug output einzuschalten. Dann google mal hiernach

#if defined(_DEBUG)
#define D3D_DEBUG_INFO
#endif

und schau mal wie Du damit

#include <dxerr9.h>

klarkommst (lib einbinden nicht vergessen)...
