Please can someone throw some light on my problem. I have made my video and burned to DVD but when it has burned some of the audio is not right with the person speaking. I use Pinnacle Studio 9.4 plus. All is ok before I make movie. I have used this program for a few years now with no problems. I have just invested in a new computer running xp as I did on my old machine. Any thoughts please. The video footage was downloaded from a Sony DCR-SR42E pal and Hitachi DZ-MV350E pal. I have used footage from both and joined them together using transitions and music. Could the source material be the problem?
