Problem with dvd burning
 

I'm using Nero 7, everything I burn goes at 2x speed. Recently, my burns have been getting a similar error near the end of the burn process. After I use the verify option, it start getting read errors near the end like at ~90%. Those files end up being corrupt. Has anyone been having the same problem like this? Is this maybe that my DVD burner is heating up?

Could be a problem in system memory. I would run memtest86+ to see if any errors show up after an overnight test. Dedicate 4+ hours for your memory to be tested. Reason as to why I'm suggesting this is because I had a similar problem just last month and found out it was my OCZ Platinum memory sticks. Went back to Corsair and no errors whatsoever.
