Clips won't finish loading

[Jeff Malo]

Can somebody can help me some of my clip dont want to load.

It was working with my last version of arena 6 and now just some of my clip and some of my effect are working. NO LAUNCHING ????

-I have quicktime and VLC install

-all the video are on my mac

- all my clip are DVX and they was working before the update

Think to know is that I rebooth my OS on my mac I dont know if something is now missing to launch the video but I dont know what could do that.

Thank

These are the Beat sync progress bars.
Is the composition Paused?

Do you have a working audio output device selected in preferences?
