NEC 2510a

I recently reinstalled my XP system and ITunes etc. There was a conflict with the DVD drive so through the registry I set it back to default and now it works, however, I have sonic record now and it says no recorder and will not all me to select it. I though maybe I will reinstall the DVD drive but to my surprise I went to device manager and it was not there. I can play DVDs fine and CDs but I am not able to use sonic record now version 7.20 which came with the computer. Any ideas please as it is driving me mad!!!
