Sorry, the OSD is not alpha-blended with this patch. I also tried to 
set, f.e. 0x80 instead of 0xff, with no effect, even after a reboot.

modprobe viafb mode=720x576 bpp=32

in /etc/directfbrc :
fbdev=/dev/fb0
pixelformat=ARGB
disable-module=lirc
disable-module=joystick
disable-module=cle266

vdr --config=/etc/vdr --video=/home/video --lib=/usr/lib/vdr/plugins 
--plugin='softdevice -vo dfb:'

Pixel format : I420

There are messages stating "uc_overlay: color-keying is enabled". I 
think this explicitely exclude alpha-blending, isn't it ?

It effectively works the same with both formats set in /etc/directfb 
(previously, AiRGB didn't show the OSD).
