i found this response in an older thread & its works perfectly now..
A small Registry edit will fix your problem. Be careful and don't change anything else while you are in the Registry.
1.Click Start > Run and type REGEDIT and hit enter.
2. Navigate to –
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
and highlight it. Then locate UpperFilters in the right hand window, (if it exists) right click on this and select Delete and then OK.
3. Under the same Registry Key locate LowerFilters, (if it exists) right click on this and select Delete and then OK.
4. Quit Registry Editor and re-boot the computer, new registry values will be created that will hopefully cure the problem.
After you remove the Upperfilters value and the Lowerfilters value, you may possibly need to re-install your burning software – but not necessarily.
