MediaInfo (0.7b) Access Violation in delphi 7

[Sirber]

setting.source_copy := 'C:\Projects\RealAnimeLE\output\temp\source.avi';procedure TAnalyze.AnalyzeAVI();
var
handle: Cardinal;
info: integer;
begin
handle := MediaInfo_Open(pWideChar(setting.source_copy));

// Look for audio
if (MediaInfo_Count_Get(handle, 2, -1) = 1) then
begin
ShowMessage('audio');

end;

// Look for video
if (MediaInfo_Count_Get(handle, 1, -1) = 1) then
begin
ShowMessage('video');

end;

MediaInfo_Close(handle);
end;
My soft crash on "MediaInfo_Open" call. Do yo know why? The procedure is a direct call to the DLL. :confused:
