MediaElement renderred to slow and with 'sort of codec problem'

[Piotrekk]

Hi

I have a little problem during displaying movie with WPF on Vista ( As
far as i remember I didn't have this problem in XP ). Having small
mavie.avi ( divx compression )
i've noticed that candle fire on movie.avi in windows media player is
displayed properly but in my mediaelement candle fire in focal point
is black. Sometimes I see such a problems when I use wrong codecs to
decode the movie.
Same problem is few seconds later with regular lamp ( only the little
elements on lamp ). I have tried different codecs so i think that's
not the problem. Really don't know
what could be the problem. The video also seem to have small lags.
Here is my code:
public partial class Window1 : System.Windows.Window
{
delegate void myDeleg();
public Window1()
{
InitializeComponent();
this.Dispatcher.BeginInvoke(System.Windows.Threadi ng.DispatcherPriority.Ren**
der,
new myDeleg(asd));
}
private void asd()
{
MediaElement me = new MediaElement();
me.Source = new Uri(@"C:\myUsers\pkolodzi\movie.avi");
VisualBrush vb = new VisualBrush(me);
vb.Stretch = Stretch.Uniform;
rect.Fill = vb;
}
}
I would be very grateful for help.
