@Hub I dont currently have a usb since my external HDD is broken :/ All I have is my HDD

Did you only start to have problems with the dvd drive after you swapped KV's? It is possible its a multipart issue and the diode is dirty/defective as well. Try flashing an old nand over that has your stock KV to see if that fixes the issue, if not it's an issue with the diode.
