problem with dvd burner

[MicRaDoT932]

i have a LG 18x Super Multi DVD Burner and when i burn dvds only a few have sound when its finished burning, but all the videos have sound before i burn them. i was wondering if anybody knows what could be causing this. And i use PowerProducer to burn them

After the burn how are you playing the DVDs on a DVD player or through the computer?

What software are you using???
