Hi, maybe some of u guys have read this like a million times but i'm just dont know what to do about it and it's driving me crazy. I just bought an nec-3520a with 2.0 external enclosure with it. The problem is, everytime i tried to burn a movie with it, it just burned with 4x speed. I've already tried using memorex +r 8x and verbatim +r 16x and it still runs at 4x. I checked my dma settings like the previous posting and still doesnt make any diffence. Can u guys suggest something else? Fyi, my comp is inspiron 4150 p4 2.0, 764ram. Thanks.
