Welcome to the forums farhanimator.
Your drive's specifications show that it is a SATA interface drive, so concerns about DMA settings don't really apply. Also, PATA optical drives show up as Ultra DMA 2 or Ultra DMA 4. Ultra DMA 5 is seen on hard drives. So, I'm not really sure what you are looking at in your settings.
You probably shouldn't have removed the drivers. If it is possible to go into Device Manager and restore them, you should do so. Or go back to a restore point prior to removal.
Just because you selected 8x speed to burn your dvds, it doesn't mean that the drive will actually burn at that speed. If the firmware of the drive doesn't allow that speed, it will drop down to the fastest speed available. Having said that, the drive is showing 8x in your CD/DVD Speed window, so the burner may simply be having problems with this particular media.
I would suggest a test burn using different software. We recommend ImgBurn for most burning tasks. It is free to download and use. www.imgburn.com
8x is top speed for that burner. We also generally recommend dropping the speed down a notch, particularly when using mediocre grade media. So try a burn at 6x in ImgBurn. It might not help, the drive may have to slow down again with these discs, but worth a try.
Better discs are available from Taiyo Yuden or Verbatim. Just don't buy "Life Series" Verbatim, get the ones that are designated AZO on the label.
