Zero, yes I have checked my cable connections. As mentioned earlier, I had replaced my original IDE cable from my DVD drives to the motherboard. That didn't help at all. I had also made sure that the jumpers are set correctly for the LG. I do not have the Sony connected right now, so the LG is set to master.
Inaris, I am currently using DVD X Copy Platinum for backing up my DVD collection. I had also tried some other DVD burning applications (1 click DVD copy and CopyToDVD). When I removed CopyToDVD, the Patin-Couffin drivers were removed as well, so I reinstalled it but currently do not use that particular application. However, this problem started well before I removed any DVD related applications.
