I Bought An Oem Lg Gsa-4163b Dvd Drive (no Software).
As Soon As I Put A Blank Dvd+rw In, My Pc Doesn’t Recognise The Drive As A Dvd Drive Anymore But As A Cd Drive. I Can View Dvd’s Fine & Can Still Use The Drive To Record Onto Cd-rw’s Ok

Yes but can you burn to it? Does your burning software see it correctly?
Do you have the proper drivers for it?
A burner require a driver? 
I think no 
What IDE drivers do you have? Many users on this forum prefer standard microsoft IDE drivers
