请教一下，为什么在我的电脑上播放的时候有音频但没有视频？xp系统vc6.0运行

这问题好有难度哦，在我虚拟机上xp，win7 x64都是可以播放的撒~
后来不知道改了什么，代码：

void PlayAVI(HWND hWnd)
{
TCHAR GetAviFile[MAX_PATH] = {0};
TCHAR FileName[MAX_PATH*2] = {0};
OPENFILENAME ofn = {sizeof(OPENFILENAME)};
ofn.hwndOwner = hWnd;
ofn.lpstrFilter =  TEXT("Text Files(*.avi)\0*.avi\0Text Files(*.mp3)\0*.mp3\0\0");
ofn.lpstrFile = FileName;
ofn.nMaxFile = MAX_PATH;
ofn.lpstrFileTitle = GetAviFile;
ofn.nMaxFileTitle = MAX_PATH;
ofn.Flags = OFN_HIDEREADONLY;
ofn.lpstrDefExt = TEXT("avi");
if( !GetOpenFileName(&ofn) )
{
//_tcscpy(GetAviFile, TEXT("C:\\Users\\Administrator\\Desktop\\Findfile.avi"));
MessageBox(NULL, TEXT("打开文件错误"), NULL, 0);
return ;
}
// mciCmd = "open " & file_name & " Type avivideo Alias avi parent " & Picture1.hwnd & " Style child" 
    // mciSendString mciCmd, 0, 0, 0 
//KillTimer(hWnd, 1);
mciSendString(TEXT("close  movie"), NULL, 0, 0);
SetWindowText(hWnd, FileName);
GetShortPathName(FileName, GetAviFile, MAX_PATH);
wsprintf(FileName, TEXT("open %s Type MPEGVideo Alias movie parent %u Style child"), GetAviFile, hWnd);

mciSendString(FileName, NULL, 0, 0);
mciSendString("setaudio  movie  volume  to  300", NULL ,0 , 0);

//mciSendString(TEXT("play  avi repeat"), NULL, 0, 0);
mciSendString(TEXT("play  movie  repeat"), NULL, 0, 0);
}
