My captures (avi at 640x480) have interlace artifacts. When I convert the avi to wmv (usually using Windons Moviemaker, also at 640x480, highest resolution), the artifacts seem to go away. Is there some built-in function that deinterlaces when converting to wmv format? I've also tried deinterlacing with VirtualDub and then converting to wmv, but the result seems to be about the same, quality-wise.
