Please post your vdr command line, /etc/directfb and the relevant part
of /etc/fb.modes.

I can see correct colours with a mode 768x576-75 (75 Hz frame rate,
maybe 45 kHz line rate), but obviously my poor 15625 Hz/50 Hz monitor
can't sync at that.  fbset my-pal-32 (the modeline from
http://softdevice.berlios.de/) produces even less readable picture.
Without an oscilloscope, I can't tell what is wrong with the signal.
Softdevice produced a black picture when I tried to use that mode
(renamed to 768x576-pal and put as the first entry in /etc/fb.modes).
768x576-75 produced sensible colours.  By switching the monitor to
composite video mode (which should normally show a black picture),
I could see a horizontal line moving vertically on the screen.  That
made me suspect that there is no valid sync signal.
