Phonon::VideoWidget/VideoPlayer issues

With my video Widget

Code:

mediaObject = new Phonon::MediaObject(this);
    metaInformationResolver = new Phonon::MediaObject(this);
    wid_videowidget = new Phonon::VideoWidget(this);
    aio_audioOutput = new Phonon::AudioOutput(Phonon::VideoCategory, this);
    //--------------------------------------------------------------------------------------------------------
    Phonon::createPath(mediaObject, wid_videowidget); // to link the mediaobject withvideo widget
    Phonon::createPath(mediaObject, aio_audioOutput); // to link the mediaobject with audio output
    //--------------------------------------------------------------------------------------------------------
    wid_videowidget->setGeometry(12,50,760,360);
    wid_videowidget->setAspectRatio(Phonon::VideoWidget::AspectRatioWidget);
    wid_videowidget->setScaleMode(Phonon::VideoWidget::FitInView);
    aio_audioOutput->setVolume(50);

the above works perfect but as the video is played it is choppy like black boxes or lines will appear and block most of the video

Code:

VideoPlayer = new Phonon::VideoPlayer(this);
    VideoPlayer->setGeometry(12,50,760,360);
    VideoPlayer->setFixedSize(QSize(760,360));
    VideoPlayer->setAutoFillBackground(true);

the above i am unable to get the video to scale to the player (760, 360) and also once the application is moved the video gets a black box as well but is long and skinny

both play video but both have issues

how would i resolve one of the solutions ?
