TiVo from AT&T Broadband

I am looking to purchase a TiVo and I saw this:

From the tivo forums it seems that it is able to control the Digital cable box that AT&T uses.

There seems to be no-other differences, other than the 40 hour capacity.

Has anyone had any experience with one of these?

I read the TiVo AVS forums almost as much as this BBS. The AT&T models are no different then Series2 except for recording capacity, buttons on the front, and AT&T logo. You do not need AT&T cable to use it.

ya i run my orgianl series one tivo with the digital cable box, and it works fine

How? When i look at the cable service selection on the tivo, I see A side, B side, and thats it. I would use the digital cable box if I knew how to do it.
