jerky playback with Video_TV in Nitotv From NAS

Something is wrong with the play back from Video_TS in my SMB NAS, It would play the movie and then stop to load for a few seconds and then start to load data from the NAS again. This problem occurs throughout a movie as often as 10 or more times per movie. I think there is a bug in either connection buffer or the player buffer itself.

Are you on a wired or wireless network?

on wired 1 gigabit LAN
I tried connect to my macbook it played smoothly
