	I done the playtree code and I was really wondering why this happen.
	I don't have any DVD drive so I can't test, but I understand what happend.
	On the beginning of the dvd playing dvd_angle is reduced by 1 to translate 
	it from a "human indexing" (1 to ...) to a "computer indexing" (0 to ... ). If you
	have another dvd try with angle 2 or 3 and you will see it decrease after each
	entry. I think it will be fixed soon, but I can't do it.
