I've been looking around for my situation, but can't find anything - sorry if I've missed it because it seems like it would be a common thing. First, I'm using DVDfab to back up DVDs using the Clone feature. I use only Verbatim DVD+R DL in an LG DL burner and everything generally works great. I have one disc that refuses to burn an audio track for one chapter. Every other chapter is fine and the original will play the audio - the copy even has audio when played in my computer, but not in my Philips stand alone (it does play R media). I guess the only thing I haven't tried is using different burning software - maybe? Any thoughts or suggestions?
The combination of Verbatim and IMGBurn seems to be the best choice for DL burning. Here's one of many threads around here. http://forums.afterdawn.com/thread_view.cfm/565256
