I had a S2 ST for about 5 years now. I just bought a S2 DT this weekend. The way the setup worked suprised me I have digital cable. Tivo set the cable box to channels 100+ with the analog tuner to channels 1-99. I went in and turned on channels 1-99 for the cable box also. This was suprising because I would rather have the clear digital channels off the cablebox when possible. My non cable box analog channels usually do not have the best picture quality (enough static to annoy me). This just suprised me since if I were less Tivo savvy I probably would have missed it. New Tivo owners will almost certainly would miss it. I do understand it is to avoid have 2 listing for each analog channel since Tivo splits the analog signal internally. I just greatly prefer the picture quality off my cablebox.
