In addition to the problem that X9S can not play .avi file with DivX5 decoding, it also can not play .wmv file with wmv7 decoding. It is not true that X9S can play all kinds of format video. Why new chipset can not play old format movie? If so, why USB3 port is compatible with USB2 port. Himedia new machine does not have this problem. Very disappointed! Is this due to hardware issue?
