I am having a problem with my HP Pavillion dv6338. It has a light scribe Slimtype DVD A DS8AZH ATA. I can play 1 commercial DVD that I know of, and the rest of them don't work. The drive makes a sound as if it is starting and then stopping abruptly, resulting in a sort of beeping screech. I was able to read a data cd and i was even able to write data to a cd, but no dvds work. I have updated drivers, uninstalled and reinstalled the drive. I even downloaded decoders and nothing is working. The same dvds that aren't playing in the laptop play on my desktop that's running Windows XP, so it isn't the dvds. I have also tried cleaning the lens in the drive and that didn't help. HELP! I'm so frustrated!
