I finally got my burner to burn a dvd without failing (cleaned the lens) but after buring it will not even recognize that there is a dvd in. I burned about 4.4 gigs pictures in seperate folders in iso and a second disk in iso/udf. nero disk info shows that there is not disk in the drive but when i stick the disk in my dvd player i can see everything. i’ve got the latest firmware all updates. drive is a pioneer dvd-rw dvr k-12d.
Try lowering the amount of data to 4.3GB on the disk for you need space to finalize the disk.
