What format is your audio file? Sometimes it has something to do with that or might be a bug in the program. Look for any updates on their website or problems that other people might of had.
Hope this helps.
My video looks great on the storyboard/timeline, but the audio got lots of drop outs, dont know why because in another programm the audio is ok.Work with Windows XP prof. service pack 2.
Maybe somebody canm help me to solve this problem.
