    Do you even have DMA enabled for the DVD drive? Without it it will be
    very slow and painful for the CPU. I also have noticed that many fast
    (16x) DVD writers must have an 80 wire cable or they won't work
    correctly and do nasty things to the system.

    Check /proc/ide/hdX/settings|grep dma and see if it says 1 0 1 or 0 0 1.
