Dvd burner problems with HP Pavillion DV9429us

Question

DVD drive can only read and burn some dvds, while my Dell E1505 does not discriminate, it reads and burns everything!! I was using easy Media Creator 9 on both laptops, then upgraded the HP to EMC 10 hoping it would make a difference. No joy!! Also, there is a driver update on the SAMSUNG site for my DVD drive, but I cannot access it. HP does not offer an update at this time, so what am I to do????    [e-mail]
