No, you do not need a new antenna for TiVo, and yes, the TiVo box has it's own tuner.

That said, some tuners can be better than others, but most are generally happy with the same antenna. Sometimes slight realignment, or in a very unusual circumstance, replacement maybe necessary, but very unlikely.

No, there is absolutely, positively, no difference in television antennas sold for years from the "HD labeled ones" - except sometimes the "HD" ones are actually more limited in their sensitivity and bandwidth - not a good thing.

The antenna does not care if the signal is analog or digital.

Thanks so much Yosemitebill! The information on the internet seems sparse when it comes to this subject. I just love the garden web forums! People are so nice and helpful. You made my day!

TiVo will absolutely work with an antenna and since you already have an antenna there won't be much more to hooking it up than connecting the antenna to the Tivo and the Tivo to the TV.

If you have a broadband Internet connection you can get Netflix, Huluplus, Amazon, and a bunch of free shows as well.

I've used DVR's from Comcast, AT&T, and Verizon and they pale in comparison to TiVo in terms of ease of use and functionality.

Thanks Mike! I ordered the unit today and am looking forward to receiving it.
