(1) Converted a PAL DVD to NTSC using ConvertXToDVD 2.0.12b.
(2) Played the DVD and worked fine on same PC that did conversion.
(3) Nero 126.96.36.199 used to copy the converted DVD but Nero never got around to the write because it rejected the DVD it read.
(4) Was able to copy the DVD using CLONEDVD to inport the DVD and then write it to the burner.
What is the problem with Nero and CXD?
