You could use the
LG GGW-H20LK. Just attach a SATA cable from the drive to one of the ODD_SATA ports.

Other members have used it successfully, and it's rated well.
BTW, I assume you haven't recorded your home movies with HDCP.
If you also want to use the drive in windows, you'd need to install the AHCI drivers. For help with this, see post #3
here.
Hope this helps.
