I have a sony dvp-sr200p dvd player and it will not play any of the downloaded movies that i have. In toast 7 i tried to burn a disk in data using (UDF) and i received a message, can't burn disk mac os error result code 13780. Other burned movies in udf seem to play fine. What do i have to do. I've tried every disk out there from dvd-r, dvd+r, dvd-rw etc.
