I just purchased the DVD Rom so I could read movies faster. The DVD is a 16X reader but with DVD Shrink and DVD Decrpter, I can only get 1.5X speed. I have a Pentium 4 2.66 Ghz with 1 Gg of ram. Should be plenty of space. I did enable DMA. I have a NEC 2500 in one bay and the Sony in the second. The NEC reads at about 4X speed and writes at 4-6X speed so that is fine. Any help would be appreciated. Thanks.
