Alright guys, my back-up dvds will play in my computer but not my xbox 360 or my sony dvd player. My old computer with an NEC burner running XP had no problems. I just bought this new computer which is running Vista and has an Optiarc RW 7173a 1-03 . I've tried various brands of DVD-R media from the good stuff to the cheap media. I've also flashed my burner with Diggy's modified 7173a 1-03 firmware and that didn't work. I also tried restarting my operating system from scratch and not allowing automatic updates in case it was a problem there. I'm ready to pull my hair out. Please, there has to be a braniac out there with some quality advice
