i have a lite on 851s and am trying to burn cd`s with nero 6.when i copy disc to disc from an image or ripping the audio to hdd,it plays the first track fine then when it goes to track 2 it goes all jittery.playback problems have been on 4 cd players only the pc will play it ok?these are all audience recorded gigs and have no encryption and have been copied ok before on my old samsung cdr.
