Hey guys, I just purchased a DVR Expander (500GB, model #wdg1s5000vn) and my Premiere will not recognize it. I tried searching for it under settings and rebooting the way it says in the manual. This is the older Expander and the box says it's compatible with the Tivo XL, and Tivo HD (released before the Premiere came out). Is it possible that it's not compatible? Based on what I've been reading, they should be compatible... Thanks!
