[MPlayer-users] Encoded resolution v. full screen

My source material is dvd/mpeg2 @ 720x480, with an
aspect of 1.78:1. I encoded to 640x480 without
changing the aspect ratio. When run, the video gets
prescaled to 854x480 and looks fantastic. If I go to
fullscreen, I start seeing some artifacts not seen at
the prescaled resolution.

I don't understand what happens when going from
854x480 to fullscreen, scaled again? Could someone
provide a general overview, or pointers to docs (I
read mplayer/mencoder docs as if they were my bible)
explaining how scaling works and if there is a way to
encode with scaling in mind?
