I have just discovered that a percentage of my DVDs burned by Nero 6.3.0.2 or 6.3.1.6 and Liteon 411s or 851s are not copyable using Nero DVD to DVD copy or even Alcohol DVD to DVD copy.
I get read errors during leadout. Basically somehow the copy made by Nero 6.3.0…2 or 6.3.16 is not a good copy. The weird thing is that they play perfect in my DVD rom drives and DVD standalone players. IF I try to do a rip using DVD decryptor, it fails 99% through writing the files on the HD.
I am using firmware FSOF (411s)and GSOC (851s) and burning DVD-R Ritek g04 media from newegg.
I need to do more testing on this, but I think it has to do with Nero 6.3.x versions and Liteons. I am going to try Nero 5.5.10.56 and see what happens.
