This cable you was seeing, is a "standard" double density IDE cable,
with 80 wires, instead of 40. The extra wires are for grounding, and it
is a _must_ for running UDMA60 or higher speeds.
Your DVD supports UDMA607ATAPI-5 speeds.
It's _normally_ not needed for running CD/DVD drives, but your bios might
have been confused, if it was set to DMA4/5 or auto, and your cable was not supporting it.
( Some cables for 133 even comes with a shield, that is to be grounded )
