Yes. Also, the Series 3 is a Tivo HD (as it says prominently on the box, much moreso than the "Series 3" designation).
Tivo themselves have blessed the labels "Series 3" and "Tivo HD" to distinguish the two models, but it's somewhat arbitrary, since each model is really both of those things.
Which is not to say they're the same -- there are substantial hardware differences. But the functionality is nearly the same.
Bad nomenclature decisions by Tivo here.
I called TiVo customer service on a different issue and mentioned this. She said that the TivoHD should say it is a series 2.
Like many CSRs, she needs to lay off the crack.
