I use Impression for DVD-5 Authoring. But when I try to exceed the 4.7Gb barrier I error out. Dual Layer is not supported by Impression. Before considering DVD Workshop (Ulead) I read into their FAQ and other Forum posts, seems their software isn't ready for the layer break either, that being a complete guessing game. The software here, Decrypter, Rebuilder, etc. seem very capable. I have officially switched to Decrypter for it's impressive ease and efficiency. What software would be capable of authoring new DVD+r-DLs? Ulead DVD Workshop claims capability but users reporting errors/patches unavialable.
