hdmi problem for v712

[flantier]

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.

Hi, which firmware are you running? It sounds like a software problem i read on here the same problems.

The version is 1.5.5 v2.
I can't downgrade because when i tried the others versions, my screen is bugged, i can't do anything. Only 1.5.5 is working fine, except this hdmi problem.
And i wanted to try the 1.4 version, but i can't find it.
