I have been using windvd to edit a skate video we have been filming/editing all summer and the movie is near end. I am starting to add background music to the video but when I do and play it the song skipps around to differant parts and back. I havent finished the video or tryed to burn it yet. Im wondering if when i finish the video the background music will be normal and its only messed up in preview mode? sum1 have any idea?
