Actually, it would be to make it clear task Verbatim why on some burners, the new 8X DVD + R DL are not flammable, unlike its predecessors, 2.4X DVD + R DL. 1. Older burners can not update the firmware (if at all possible), no DL 8X burn even when using appropriate software - even if they are capable of single layer DVD's to burn with eg 16X. 2. It is important to ensure that the software used supports 8x with DL's. 3. A few burner manufacturers give a damn about the compatibility with Verbatim. Therefore, when buying ensure that the appropriate compatibility is ensured. If attention is paid to these above points recorded, the DL's Verbatim can burn with the usual reliability! Advantage: baking at a 8.5GB only about 20 min.!
