There two version of the My DVR Expander, the ESata version would work on the Tivo Series 3 and the USB version would work on a DISH Network ViP Series HD DVRs. If you have the VIP series you would be fine.

Some other DVR's may work with as well that are not listed on the website, Like Directv advertises the esata DVR Expander compatible with their DVR's , i guess some of them, but WD will support what is listed on the website.
