I recently replaced my DVD burner with a Liteon LH-20A1H drive. My old drive is a Benq 1655 and had no problems copy my own DVD's. When I replaced it with the Liteon drive most of the time it would only start burning and only burn the first few minutes of the movie and then kick with the message the burn was not sucessfuly. I have tried every type of media that I use. (verbatim 16X, ritec 8X, princo,). I shipped the drive back and it was replaced with a new one but get the same results. Put my old drive back in and works perfectly. Can any help with this. Willie
