I got a laptop about 8 mths ago with a cd burner. it plays cds/dvds but it wont burn. says no cd burner installed. I hear this is a common problem with XP. I followed instructions on microsoft to change a value in the registry.

It said to go to HKey_local_Machine/software/microsoft/windows/explorer/cd burning/drives

but all i got was
HKey_local_Machine/software/microsoft/windows/explorer/cd burning/
in this there was AudioBurnHandlers and ExcludedFS

any ideas on this
