I've installed Lubuntu 13.04 upon an old HP laptop, and it works great. Unfortunately, when I try to access a shared directory on a PC inside my home network, on which Ubuntu 12.04 is installed, I can't stream videos stored in there.
First the problem was that with PCManFM I was unable to access the directory, so I installed Nemo and Nautilus. With both I can view and copy files, but the videos (or MP3) are unable to stream. I also tried with VLC but without luck. If I copy these files into the laptop with Lubuntu, I can view them without problems.
Then, if I try to play a video file from the shared directory, VLC (or any other video player) opens regularly but the screen remain black and nothing is reproduced.
Any idea ?
