You could try ShellExecute to run default AVI player:

DECLARE INTEGER ShellExecute IN SHELL32.DLL INTEGER nWinHandle,;
                                               STRING cOperation,;
                                               STRING cFileName,;
                                               STRING cParameters,;
                                               STRING cDirectory,;
                                               INTEGER nShowWindow
ShellExecute(0, 'open', full_path_to_your_demo_avi_here , '', '', 1)
