Last month I opened up the machine and disassembled the components all the way down to the DVD drive and vacuum every part to rid of dust. It has accumulated quite a thick layer on the circuit boards and fan. To my surprise the DVD lens was clean with no dust on it. I re-assembled the parts, the symptoms remain.

I was already looking online to find a replacement, when I thought why not look online to see if there is a solution for this. If I am having this problem then someone else must be having the same problem. To my surprise, there are many documented problems on this issue regarding these Sony DVD recorder models (RDR-GX300, RDR-GX315, RDR-GX330 just to mention a few). Namely the DVD drive not recognize the disc.
During one search I found a posting on Fixya.com stating my exact problem and steps to fix the problem. Since I had already opened up the machine once already, it was very easy to get down to the anatomy of the drive.
The laser carriage attached to the slide rails was loose on the grub screw side (If looking from opening tray toward the back it is on the the left side of the rail). All I did was finding an hex key small enough to fit in the screw and tighten it until it touches the rail then back it off about 1/4 turn just so the laser carriage will slide freely on the slide rail.

Reassemble the parts and Done! So far it has worked flawlessly, just like a brand new machine. If you have the same trouble, hopefully this will help!
