I just got my X9S and rather disappointed by its performance after I tested with some 3D BDISOs using the media centre. Both video and audio keep stuttering even though they are played from my NAS via gigabit LAN connection. This is bad compared with my old Himedia Q5 Quad which can handle them perfectly. Scenes with high bit-rate (3DMVC and HD audio) are worse. I am not sure if this is bandwidth problem, but Himedia can do it well with the same setup. Is there any trick/tweak on X9S that I can try to improve? Thanks.
