I am using the Texture3D-sample from the DirectX8.1 SDK. The sample detects the right resolution of my videos, but on the created texture, the picture is surrounded by a black border. How can I fix this.

I think this is caused by the texture adressing mode. IRC you have to set it to clamp but I'm not sure.

I don't think it is the texture adressing. The sample creates a texture with the right resolution, so the video must fill the complete texture. Here is an example:

And that would be right (made with Virtual Dub):

It's quite possible that the black border, at least on the left and right, are overscan from the video signal. It may very well be what your video capture card delivers through the capture application.

The keyword is "overscan".

The video is downloaded from a website and the black border on the left is right, but the other borders are much too large.
