DVD Burner is reading/writing at very slow speeds

My brother called me the other day about a problem he is having with his DVD burner (Lite-On 20X, not sure of the model number). He said all of a sudden it has started to read and write at very slow speeds (it will only burn at max of 2X). He returned to the store which it was purchased, replaced it and is still having the same problems. He uses DVD Decrypter for burning DVDs and says that also the device buffers are also jumping around erratically. I have never experienced this myself so I don’t know how to fix it. Any advice would be a big help (especially for him).

Hi and Welcome,

I suspect, the drive isn’t running in DMA mode any more. Please read this: http://club.cdfreaks.com/showthread.php?t=101616
