Yes, I have the sony dru500a which also burns at 4x speeds. I brought this thread up for all that have a 4x dvd-burner and wanted the high speed media, this thread wasn't meant to be for the people with older burners. Why on earth would anyone pay that much more for media that they can't burn at full speed? It's a dumb debate going on in here. Don't worry about the high speed media destroying your drive. If you're wasting your money on expensive high speed media that you can't use, you deserve to have your burner fried.
