Having a problem trying to grab a snapshot of a movie to use as an icon

[TwoGunBerg]

Hi All;
I've been looking on the web for a way to programatically open a video/movie file and grab a snapshot so i can use it for a thumbnail of the file in my app. I have found a few ways to do it on the web but none of them seem to work for me. I have tried using:
@ QPixmap image = QPixmap::grabWindow(tVideoWidget->winId());@
All i get is a black image. I have tried:
@QImage image = tVideoWidget->snapshot();@
With this i just get a null value for the image. Here is the method i have using to try to grab the frame:

@QString Utilities::GrabSnapShot(QString aMoviePath, QWidget* aParent)
{
QString tPath = Utilities::AddThumbnailToPath(aMoviePath);
QString tThumbnailPath = RemoveExtension(tPath).append(THUMBNAIL_EXT);

//get metadata information from the media file.
Phonon::MediaObject* tMediaObject = new Phonon::MediaObject(aParent);
Phonon::MediaSource* tMediaSource = new Phonon::MediaSource(aMoviePath);
tMediaObject->clearQueue();
tMediaObject->enqueue(*tMediaSource);

tMediaObject->seek(5000);
tMediaObject->play();
// or setCurrentSource5.m_MediaObject->play();
Phonon::VideoWidget* tVideoWidget = new Phonon::VideoWidget(aParent);

Phonon::createPath(tMediaObject, tVideoWidget);
tVideoWidget->show();

QPixmap image = QPixmap::grabWindow(tVideoWidget->winId());
image.save(tThumbnailPath);
delete tVideoWidget;
delete tMediaSource;
delete tMediaObject;
return tThumbnailPath;

}@

From some of the posts i have seen it appears that these might be bugs. Is there another way of being able to grab the image/frame? thanks for any help.
