Clone DVD2 records video but no audio

[Jazzy0]

I am new to DVD copying and so I am using the 30 day trial version of Clone DVD2 on a Pentium 4 machine with XP Professional OS. I am able to copy the video part of a movie fine but there is no audio on the copy when I play it back on my DVD player / writer on my computer. The original DVD plays fine on my computer. I also get a disk error when I try to play the copy on my stand alone DVD player. I am using DVD+R disks. Does anyone think that using DVD-R disks will make a difference? I also have AnyDVD installed to work with Clone DVD. Does anyone have an idea as to what is wrong, or what I might be doing wrong?
