I forgot to mention, that the OSD rendering (for example fonts) is done by 
VDR. I only use xine_osd_draw_bitmap() to get the VDR supplied data to screen.

What can I do about that issue?

BTW: The "shadows" you see for example in the OSD text are not a matter of 
taking the photograph, they really appear on screen. Is there a better way to 
take a screen shot of a xv-window?

Please explain that a little more, if you think, that I can do anything about 
that issue in the supplied OSD data, because the same data looks quite ok with 
xshm.
