I can't imagine hooking up my 4 HR20s to a computer. I like the Internet, and I don't mind using a computer for a purpose, like writing a post, but I hate working on them. I have been using computers since 1962 and I am just tired of working on them. I guess I just don't see the purpose in networking DVRs. I'd be interested to learn how you use your setup and what the benefits are. Anyhow, I wasn't advocating changing HDs as useful, what I meant was simply that I thought it could be done on similar Series 2 TiVos.
