I have been trying for days now to create a "Best Of" music DVD from several that I have and I am finally getting close I think. Last night I used DVD Shrink’s “reauthor” to selectively rip certain songs from several different music disks to my hard drive as .iso files. I then used Nero 6.6.0.5 to create a new DVD with these files. Some of the songs had their sound and some did not have any sound even though all the video worked. I am thinking that it might have something to do with some DVD’s being 5.1 and others being 2-channel sound and Nero doesn't handle the Dolby. Does this sound like it might be the issue. Maybe I should be ripping them and re-recording them differently or with different software?……..Thanks, Mike
