Start reading the tivocommunity.com website. Then, visit www.weaknees.com for more info.I got one of these last summer. Sadly, the hard drive failed shortly after getting it, and I learned that TiVo doesn't ship replacements to Canadian addresses. Still sitting on my broken Tivo, I think I will crack it open at some point and try to get it working again by replacing the drive, but haven't gotten the courage up to try that yet.
Don‘t mess with it until you’ve read up at these two sites.
Creating a new drive from an image is fairly easy from tivocommunity instructions.
And try the zip code ‘00000’ for Canadian sources.
