Most likely your problem is there is no way for the warm air entering those bedrooms to get back to (return to) the furnace. The fact the warm air can't escape the rooms (doors closed)means the air pressure in those rooms increases enough to make inflowing warm air decrease.
Easiest solution is cut the bottom of the doors. That way air can escape the rooms by flowing under the doors. Adding a true return duct to each room might be too expensive but would be the best solution.
