I just received 2 Tivo Premiers (refurbs) from woot.com, and am going to use them to replace 2 Tivo HD boxes.
I started looking for 2 of the WD My Book AV 1TB external drives as I'm using 2 of the older 500GB versions (1 on each of my Tivo HDs).
Well surprise, the My Book Av 1TB expander is out of stock everywhere at this time.
Here we are currently, almost 1/2 way through 2012, and no availability? Wow.
I s'pose I'll use my old 500GB units in the meantime w/ the new (refurb) Premiers, but I know I'll lose any programs recorded and stored on those, which is why I wanted to get the new storage now.
