I have the same exact computer, and I have received that error too, however, not everytime. What I have done to mitigate the problem is before I burn a DVD, I reboot the computer if I was doing anything at all prior to the burn. I also make sure my anti virus and spyware SW are off. I get rid of all of the extra stuff in my system tray, and I do not have any other programs running. I have also permanently disabled the Roxio Watch tray and Drag to disc from start up. I then burn to the hard drive. After that, I will use disc copier to copy the ISO file to a RW DVD and try that in my DVD player to ensure I have a good burn (saves a lot of money, DVDs, and guess work). If that works, I use disc copier to make my final DVD. Sometimes I will get a simliar error at the end of the burn process, but the DVD seems to be okay and plays anyway. Until HP, MS, EMC, NVIDIA or some combination of the four vendors works together, I don't have hope for a fix. They all would rather point a finger at each other rather than fix the problem. Let me know how it goes.
