Oh, and btw - the second part (replace English voice + text with Dutch) should be done as follows:

Either use the original ISO, replace the navboot file you created (English text replaced with Dutch), rename the nl4f.tsf (Dutch voice) into nl4f.tsf2, rename e4f.tsf into nl4f.tsf and rename nl4f.tsf2 into e4f.tsf (in /V_2/language/0105 and /V_2/Voices/0506 folders), replace the image with the one you like, burn the ISO and listen to the Dutch voice, with Dutch texts in the German mode and boot your favorite image

Or use my ISO, replace the navboot file you created (English text replaced with Dutch), rename the d4f.tsf (Dutch voice in German file) into d4f.tsf2, rename e4f.tsf into d4f.tsf and rename d4f.tsf2 into e4f.tsf (in /V_2/language/0105 and /V_2/Voices/0506 folders), replace the image with the one you like, burn the ISO and listen to the Dutch voice, with Dutch texts in both the English and the German modes and boot your favorite image
