I always used Nero and enjoyed the 5.x versions, but now it seems it's spoony sometimes, though it works fine in general. The question is: does the burning app really have an influence in C1/C2 (PI/PO) errors (besides occasional bugs that one version may have)? If so, is Nero usually a bad performer in this aspect?
PS: I also used burnatonce for a while one year ago, but I came back to Nero... I'll try the dvd support in burnatonce via proDVD once I receive my key.
