DVD-A requires a specialised. DVD-Audio player. I guess that you,re just trying to burn a DVD to play on a standard player. I'll download Imgburn ontto my windows laptop over the weekend and see if I can figure out where you're going wrong. Btw, I doubt that lplex is malware and think that webroot has given a false +ve (it happens)but for your peace of mind, I can understand you not using it.
