Some video files from another partition or volume does not display in some video displays but display on another and crashes on others.

Seem to play on these video players:

* vlc
* smplayer
* gnome-mplayer

Seem to have some issues in these video players:

> 
> totem -some videos are play while others not banshee -some videos are
>  play while others not bangarang -few videos are play while others not
>  and it crashes and happens also in home folder of filesystem dragon
>  player -crashes and seem not to display any video and happens also in

**Why this happens? Is this a bug?**

This error occurs on ubuntu 12.04 beta 2.

On ubuntu 11.10, every video display play all the video from another partition or from home filesystem.
