hello everyone.. thanks for reading my post. I recently noticed that sometimes when backing up a DVD, the DVD will sometimes have dark discolorations on the bottom. I played one movie I burned that has these discolorations, and it played fine. But the discoloration bothers me. Usually it's just a dark spot or 2 on the bottom of the DVD but sometimes it's a streak. I have noticed this when I burn at 4X. When I burn at 2X I don't notice the problem. I will start burning at only 2X.. but does anybody have any idea why this is happening? I have a SONY DRU510A 4X DVD Burner. Thanks. EDIT: I have noticed the problem on 4X Samsung media and Ritek GO4 4X DVD-R.
Hi, So it appears there's something not good with burning at 4X doesn't it? What firmware version is your DRU510A running?
Thank for the reply. I forgot to mention I actually have a Sony DWU14A. However I had problems with the original firmware. I did research and was advised to upgrade to the 510_a11a Firmware. Now my system recognized my drive as a DRU510A. The thing is I burned over 100 discs with the new firmware no problem.. I just now started noticing the black spots. I always used Ritek GO4 then I thought I had a bad batch, because of all the black spots. Then I got some Samsungs, same thing. I have tried some TDK's and they seem to be OK. I use DVD Shrink 3.2 with the Nero option checked when I backup movies.
