DirectShow Mpeg2 playback in secondary monitor

Hello.

I'm changing a perfectly working PlayWnd directShow sample to play an mpeg2 file on the secondary monitor of my pc.
I have two monitor, the second one extends the first one at coordinate 1240,0.
I changed the PlayWnd sample to create the window at 1300,10: the window lies entirely on the second screen area.

When I select the movie file, the audio starts but the playback video area is black.

It starts drawing only if i move of some pixels the window with the mouse by dragging in the title bar. I tried to reproduce this with a MoveWindow() but it does not work.

What is happening ?
Do I have to address the GraphBuilder to display in the second monitor explicitly ?

Thanks.

I don't know exactly how you specify it, but it likely has to do with the Overlay based renderer.  I can't remember which way it works: either overlay has problems with a secondary device, or you have to use overlay for the second device.

Sometimes, it also depends upon the driver providing proper support for the secondary display.

I don't have direct experience with the DS graph creation, but you should look at what renderer you can choose from, and maybe whether the renderer is somehow 'bound' to a particular device (which D3D would do...).

The PlayWnd sample does not choose explicitly the renderer.
The sample (it's a sample of DX sdk) does start up everything with

CoCreateInstance(...FilterGraph,... IID_IGRaphBuilder, &pGB)
and then
pGB->RederFile();

When I move the window, nothing more is done except positioning the output window itself on the secondary screen.
Do you know excactly what functions are used to choose explicitly the second overlay renderer ?
