pb audio underrun, help traduction de la console ?

bonjour,
après importation d'un .avi de 40 minutes, lecture saccadée du rushe, fenêtre moniteur clignote et se fige, aléatoirement fonctionne dans composer, sautes multiples de son et désynchro...

trouve pas de solution
ci-joint script de la console, est ce que ça vous parle ?
merci!

NB: tout marche bien habituellement.
