This a problem which I had on my old B&W G3 and it had a number of causes. The major cause seemed to be the bus which the extra drive was attached to. I originally installed the extra drive as a slave to the main drive and I could not get past the problem you are reporting. I installed a new ATA card in one of the PCI slots and attached the extra drive to it and that did the trick. Also make certain that the energy saver is turned off as well as all other applications. De-fragmenting the drive which contains the video files will also be helpful.
