CD/DVD Burner will burn CD’s but not DVD’s, Help?

I can write/burn to a CD but not a DVD. I get the following error…”Failed to burn this disc (Extended error: 0x80041024).” I have an HP Pavilion dv6 Notebook PC with a DVDRAM GT20L DVD/CD-ROM drive. I am running Window 7 Home/64. I have uninstalled the DVD/CD device and reinstalled it with the latest drivers. I am using new Memorex DVD+R media. I also tried Staples DVD+R media.. Still…No Luck! I’ve tried a lower burn speed and have all the latest firmware and driver updates. I would appreciate any ideas or assistance. Thanks…
