Hello I have the v712 for 1 week, and yesterday i wanted to try the hdmi output. All was ok but when i tried to watch a movie and it was unwatchable. The play was not smooth at all and the sound was "cut" (i dont know the english word for what i want to say, according to my translator its "jerky"/"chopped") When i try to watch the video without the hdmi, it's fine ! Am i the only one who have this problem or is it a known issue ? Then, is there a fix or something to repair that problem? Maybe something i did wrong .... Thx guys.
