process not running

Hi everybody,
a couple of days ago I realized that when I’m working with Cubase (7.7 trial) there are always some processes that seem to be blocked. (see attached image)
They all are concerning video aspects but I’m not working with video; I only opened a soundtrack project embedding a video once, from my old pc, and everything was ok.
I’m a newby in the mac world, as I bought my mac mini just month ago, so I can’t understand everything…

Any idea about this?

Thanx,

arfo
