Hi people. 

I tried geexbox (is that a gee , Xbox :-).
Works really nice, but I think it don't use X11, (framebuffer maybe).

The following option worked for me:  [1]
Option "NoYV12" "true" # or "yes"
Done ! No more purple bar (at  _right_(!) of the video).

In the device section of  /etc/X11/xorg.conf:

Section "Device"
        Identifier      "Silicon Integrated Systems [SiS] 630/730 PCI/AGP VGA Di
        Driver          "sis"
        BusID           "PCI:1:0:0"
        Option "NoYV12" "true"
EndSection

VCD- works, full screen , no purple bar.
DVD - slow (not  sure about my DVD player reliability) . Maybe playing with 
zoom / scale /sound options of mplayer can make it work (or upgrade my memory , 
128M is no fun :-).
