This is my first post, and I see I already made a mistake, by not saving the Nero error msg. I printed it instead. Anyway, I've been trying to copy an unencrypted dvd. I've made three coasters. I'm using Nero 6.X, updated to the latest version. Lite On burner, XP. Media tried has been Phillips, Princo, and Teon. It says burning failed at 4X. It gets about two thirds through before stopping. I even tried running it through dvdshrink, and shrink stops after it encodes 68%. It doesn't give an error msg, just stops. What other info do you need, or do I need from you experts?
