I recently baught a OEM Pioneer 107D DVD Burner. I have installed the firmware off the pioneer website. I baught some comp usa DVD Discs. When I put the disk in, the windows program asks me to open the writable device. So the drive pops up but it says there is 0mb free of 0mb. So I dont know if there is a problem with the burner, the disks, or am I missing something. Do I need more softare aside from the firmware. I have used DVD Shrink to get files that are about 4.7gb. Now I just want to put those files on a DVD. My burner see's the cd-r's have empty space on them, why not DVD's?
