strange things happen… having two renderers connected to the same quad with videotexture & filestream.
everythings ok as long as these renderer are on the same monitor. as soon as i put one on the second screen, the renderer on the first monitor shows the video skipping between two frames and doing some ugly transforms…
this is a known bug.
by current design video (directshow graphs) are working on only one device. however, if the two monitors would share one device (which is in spanmode) then the direshow stream should work.
