The figures given for the "best" preset on 770-encode are the best acceptable quality (judged by me, admittedly) on the built-in player of the 770.

mplayer has yet to be optimised for the N800, but Serge has said here that he's almost to the point of 640x480 resolutions on the 770.

I've yet to determine the best quality for the N800, but 352x288 scaled looks damn good to me on the N800's screen. 400x240 in mplayer on the 770 looked ace (and *almost* plays back on the built-in N800 player).

These are damned good devices for video.
