Can you do a test of your burners? Run CD-DVD Speed (see where download in my signature if you already have not it), insert a blank media on the drive, and then select the "create disc" tab. Select both "Simulate" and "Burn Image" options, select a burning speed, and finally press the "start" button.
At the end of the test press the little floppy button on the high right corner and save the pic as PNG, and finally post the pic here.
If you can "sacrifice" a disc, it will be better to not check the "simulate" option, to actually write the disc.
To burn a file on the disc you must use an ISO or a NRG file. If you don't have an available file, you can uncheck also the "burn image" option.
