CD & DVD problem with XP

I thought you had the answer but did not have any upper or lower
filters at HKEY_LOCAL_MACHINE\System\
CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
that I could delete. There were some upper in lower filters in
classes other than {4D36E965-E325-11CE-BFC1-08002BE10318}, do I delete
those?



This is a well known problem with XP, if you cannot access CDROM, DVD,
CDR or CDRW drives or get a Code 31 or 39 error in Device Manager then
the solution is to run Regedit and delete Upperfilters and
LowerFilters at HKEY_LOCAL_MACHINE\System\
CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
and then restart the PC.

If you have recorded a CD in XP and becomes unreadable or files are
missing then download a CD Burner update from
