I downloaded Director Suite 3 last night (I have a Live subscription). I haven't had time to run tests but looking in the 'Create Disc' module, in blu-ray -> h.264 there is the option to burn in 1920x1080 50p. There is a warning that not all hardware will play the discs but that is for each individual to check. The PS3/4 and 2011 onwards Sony blu-ray players certainly work.
