[Maete]

Hi,

I am usling the latest version of vti image on My vu+ duo.
I am playing movies from My network share on My pc usling the media player or the movie list. When fast forwading the sound disappears from the movie. To get the sound back i need to restart the movie. Does anyone Else have the same issue or à suggestion on how to solve the problem?

Thanks in advance.
