I said I'm using DVD43 with my roxio disc to disc copy software because it's fast and one step, and I don't have copy protection or region code issues I didn't say that it's better, beside that ImgBurn has to compress the video signal to comply with the law so you're not getting the identical video quality.
I have a regular copy software that I can use with the following protection remover in the link bellow and I don't have any probleme at all, I copy DVD's that excedes 4.5GB to DVD Dual Layer and the ones less than 4.5GB to DVD-/+R and I don't have any problem of copying disks and it takes only one step not two like the DVD Decrypter.
