I installed SP2. Started Nero 6, saw the compatibility message, so I downloaded and installed the update from Ahead.de. Tried to burn DVD, failed. Used Test Drive under Nero and got a Spindle Servo Failure when testing transfer rate. This somehow only happens to DVD. I used Nero and OptoRite to burn a CD compilation and everything worked fine. Could this be my disc problem, SP2, Nero? P.S. I used search and found a related post and a link by MS that solves problem of missing files under XP when disc is burned under 98 or 95, but it won't installed on SP2. It says I have to install in under no SP... =( The file is Q320174_WXP_SP1_x86_ENU.exe (Windows XP Patch: CD Burning Update). Any ideas? should I uninstall SP2 and SP1 to install this? Thanks a lot.
