DRU-700A not burning DVDs anymore, but burns CDs fine

I have a DRU-700A with the latest firmware (VY08) that burns CDs fine, but stopped burning DVDs. It's done this before, and then it started burning a DVDs fine once more, and now it doesn't work again. I am using Nero 7 and I don't have Roxio installed. Sony DVD-R media at the moment, but nothing else really works so I know it's not the media. I actually watched the burn progress today and noticed it didn't get passed an IFO file, which was one of the really small ones. It took a couple of minutes just on that file and stopped burning. What can I do?

Have you tried reducing your burn speed on DVDs to 4x?

 

yeah it didn't help
