Dear all, First of all, thanks for all the reactions. They really did clearify the problem. Unfortunately, it did not solve the problem.
This is what I got: - the original DV files have no synchronization problem when played with totem; - when imported into a new project (file as one clip on timeline), audio and video seem synchronized, but whenever I press play, it quits so I can not be sure, but both tracks are of equal length - I have not had this problem in Adobe Premiere Pro - I have many short clips in the project, title and fades, but no other effects - I do not know how to fix this problem - I can email the xml file, if this would help. Thanks, in advance, once again.
