Im kinda new at this , maybe check the DMA. I had the same prolem w/ my drive. I turned the DMA on and it fixed it. hope this helps.

 

Try cleaning the DVD lens. Make sure your drivers and direct X are all up to date for your audio card. As far as your burning times being slower than before you need to check your DMA settings for your drive. http://home.comcast.net/~bbmayo/DMA.html
