Is the above information obtained before you have burnt the discs ?
Is there a newer firmware available for your drive ? I tried a quick search over at www.rpc1.org but couldn't find anything, you can look yourself from the ImgBurn Gui window. Right click where you can see your drive (left of window) and then select Firmware Update from the list, if there are any available it should find it for you. Maybe an updated firmware will fix the problem.
