It's a slim ATAPI connection.Those are the slim ribbon cables that are used in Laptops to keep the slim form of the Dell XPS 200. The hard drive was connected via a SATA cable and that slim DVD Drive was connected with this slim ATAPI cable. I dont see any regular IDE connections in that video at all.
From what i gather you would need this:
Slim ATAPI to Standard ATAPI Adapter, for using a laptop CDROM/DVD/CDRW in a standard slim drive bay-Best Computer Online Store Houston Buy Discount Prices Texas-Directron.com
Where the 1 side connects to the drive and the other side has the connector for the IDE cable.
