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.
