I have a problem that is driving me crazy! I have a Intel D915PBL Motherboard and am trying to run two dvd drives. One is a writer and the other is just a plain dvd drive. When both drives are in the system I am only able to transfer books from DVD to the computer at around 5 to 10x. However if I have only one drive in the system either one transfers around 16x. I need to transfer using both at the same time. I have tried the following:

Two Different drives on the same ide cable
Two DVDRW Drives on the same cable
One IDE DVDRW Drive & One SATA DVD Rom Drive


It does not seem to matter what I do. With two drives in the system it will only transfer the data at around 5x. I have a friend that has a slower computer and no problems doing this. My motherboard only has 1 ide port. Any input would be greatly appreciated!

System Specs are as follows:
Western Digital 250GB SATA 3.0Gb/s 7200rpm, 16mb cache Hard Drive
Intel Pentium 4 3.4GHz 550 LGA775 1mb Cache 800MHz
G.SKILL 1GB 240-Pin DDR2 SDRAM Unbuffered DDR2 533 (PC2 4200)

Is DMA enabled on the IDE channels?
