My copy of Nero worked fine before installing XP SP2 !! I think I may have a solution. This appears to be caused by the process RMADEC.EXE that is spawned by Nero and then freezes on some systems. To get around this on my system I have written a batch file as follows: @echo off cd c:\program files\ahead\nero start nero.exe @ping 127.0.0.2 -n 5 -w 1000 > nul taskkill /F /IM rmadec.exe For those of you unfamiliar with batch files, simply open notepad and enter the text shown above. Then save on your desktop as nero.bat. Double click to start it and that should be that. The @ping line causes a delay of 5 seconds. This should be enough time for the RMADEC process to start before the taskkill line trys to stop it. If you have an older machine you may want to increase this from 5 to 6 or higher. If your not comfortable with batch files then simply open task manager before launching Nero, Start Nero and look for RMADEC.EXE in the process list and end it. Nero will start as normal. Comments please, let me know how you get on..... Happy Burnin !
