Until a few days ago I've been using Nero 6.6 (final upgrade from the web site) on both a Sony DRU-810A and DRU-830A with pervasive failure to write a Dual Layer disk playable on any console player, though the disks play perfectly on a computer. Disk manufacturer mattered little, even highly regarded Verbatim (MKM-003)produced mostly coasters.

With ImgBurn, all my burns, including Verbatim 8x (MKM-003), Sony 2.4x , Memorex 2.4x, and Fuji 2.4x (all RITEK-D01), work perfectly. All these blanks were taken from the same spindles producing coasters using Nero. All this time I though the problem was media!

Nero has a serious Dual Layer writing problem (both with isolation of IFO and BUP files as well as the layer break, as discussed elsewhere in these forums -- THANKS ALL for these posts). ImgBurn is an amazing program that completely blows away this major software house's product. LIGHTNING UK is a master of the highest order (which many of us already knew anyway from DVD Decrypter). I wonder how many of the poor performance reports for various DL media were in fact due to the writing program ...
