Hi, Im trying to render video using SlimDX. The video that is rendered contains smooth edges whereas when the same video is rendered using ManagedDirectX seems to be Jagged. Could you please let me know whther by default ManagedDirectX turns off Antialias. If i want to turn off AA in SlimDX how to do it. I have tried SetRenderState with multisample antialias and line. still no use. Thanks, Aswin.N.Paranji

Antialiasing in D3D only affects polygon edges, which I suspect you won't have many of in your video.

What you want to change is the texture filter. Try point filtering to get blocky results.
