jagged edges to uv mapped video

hello.
i have uv mapped a video to a plane, but the quality of the video gets considerably worse in quality and edges gets jagged. turning up my osa to 16 doesnt work either.
is it difficult for blender to handle such a task or is there some way to repair the quality-loss?

newbie

thanks
