Good Afternoon All

I have another Pinnacle 10.5 issue that I'm hoping you guys can help me with. I'm doing a project for work and I have video clips recorded with a camcorder, burned onto CD-R and brought home to work on. Most of the clips worked with no problem but on a couple of the clips at at certain point the sound goes out of sync and gives the appearance of watching a badly dubbed kung-fu movie. The originals of the clips work fine and I don't have the problem with the sound until I import then onto Pinnalce's storyboard. Is there a way I can fix the sound or will I have to re-record the video and hope it doesn't happen again.

Thanks for the help
