I'm trying to read .avi files, but I can't!! I get this error..

??? Error using ==> feval
Undefined function or method 'figure1_ResizeFcn' for input arguments of type 'struct'.

Error in ==> gui_mainfcn at 96
        feval(varargin{:});

Error in ==> act_ive_gui_new at 42
    gui_mainfcn(gui_State, varargin{:});

??? Error while evaluating figure ResizeFcn

Any idea??
Thanks!
