Nero audio out of step or sync
I notice this happens on several versions of Nero Vision. Be sure to get the update from the Nero site since this fixes that problem. There is one other possible thing you can do if it does not fix the problem. You replace an
audio file called Neaudio.ax in the Nero Vision directory under programs. Copy the original one first to a safe directory since this might not work in all cases. You will find a replacement file at ES5 if you go into software and enter the above name. The new file is about 500k and the old one is about half that size. Earth Station 5 you have to install first of course and search under software for it. Kazaa might have it too. Now keep in mind this may not be necessary. Try the upgrade first and cut a movie and see if the sync problem is gone. I did the two steps so am uncertain which was the fix but the sync problem is gone.
