if you have the latest tuner software and drivers then you have reached the end of the road.
Generally they dont make new versions of firmware for video cards (not like they do for motherboards)
all you can do is flash it with a firmware that was made for a different 9800 Pro AIW that did support PAL BG/DK. I dont know if one even existed that supported the PAL you need.
If You = X, Rock = Y, Hard Place =Z
then Y->X<-Z
or
ROCK----YOU----HARD PLACE
