Advertisements I am seriously thinking about purchasing a TiVo to use with Comcast digital cable (+HD) instead of using the Comcast DVR. A few questions I have, though: 1) Can I use TiVo for HD programs and then send those to my Pioneer 220-S DVD recorder? 2) Are all TiVo machines 2-tuner capable or should I shop for a particular model? 3) If anyone has had experience with the Comcast DVR, which would you suggest to be better...TiVo or Comcast? 4) I've done some reading on initial set-up and I understand I have to use a landline to do the initial set up. But, after that, can I then use my wireless network (or ethernet) to do the connecting? Thanks alot for any answers/additional information. I appreciate it!
