I need to raise the audio level on dvd's I burn. I have not had a problem until about the last 3 months. I have been copying music videos from VHS tape to DVD using a stand alone Lite-On HD-DVR. Then I load the DVD to Nerovision and edit out each individual video. For some reason the volume is to low now. It worked fine for a year or more. No equipment changes. If I have NeroVision open and in the edit mode and right click on the video, then properties, there is an option to raise the audio from 100% up to 200 %.. It makes no difference what I do, the final audio is only about 50% of what it should be. Any ideas?
