Problem With Nero using the Copy DVD option

[milldakill]

I have burned about 65 DVD+Rs in my TDK 420N (4x DVD+RW ) All of them have been movies and all have them have been burned with nero using TDK 4x DVD+R media. When making new Video DVDs using the Video DVD option in nero i have not burned one coaster, but when using the Copy DVD option in nero I have burned 2 coasters now. 2 may not seem bad but i have only used the DVD copy option about 10 times. Has anyone else had this problem?

Does it break during the write, or are the discs just not playable?

[milldakill]

It writes fine, but the disc will not play in anything, even the DVD burner

Hmm thats pretty bad. Can you see anything on the broken discs or do they just not initialise?

[milldakill]

nothing, they dont read at all

You cant even read the disc info in nero or whatever?
So it doesnt show the disc contains 1 session, 1 track etc?
What does nero say about the disc?
