[MPlayer-users] scaling and resizing for -vo

[Luis.F.Correia]

I have a small question that will take some time to explain:

mplayer playing a divx movie using -vo dxr3.

I have been told that the optimal resolution for the DXR3
is 720x576 (PAL).

Let's imagine I have a Divx movie that was resized to
640x272. This aspect ratio is (if i'm not mistaked) 2.35:1
which is normal for widescreen cinema movies.

Mplayer does a small scale job which cuts out the movie. It looks
good but I would like to have it in another way, no scale and only
display it bit-by-bit.

I cannot explain this better without a sketch.

    |        |      the optimal viewable area  |        |
    |        |    of the DXR3 with no extra    |        |
    |        |    scaling or processing        |        |

    |        Subtitles could go here without having     |
    |        to worry about shading / alpha blending    |
    |                                                   |

This could of course be possible to do for every -vo device.
I think that DGA works this way, but I'm not sure...

I really hope that this is possible.
If it is, (and i have spent some time RTFM'ing) how should I do it?

Thanks for a GREAT player. Far better then xine or other crappy 
players out there!
