How Do I Use Hd Cable With Regular Tivo On 1080p Hdtv?
I have a regular TiVo Series 2 box, with comcast HD. I was wondering how to best set this up. I dont know if you can put the HD cable to the TV & out A/V to the TiVo, or what. PLEASE DO NOT tell me to just get an HD TiVo, we’ve already spent more than enough getting a 50″ 1080p TV with the service. Thanks.

The reality is you can’t record HD stations with your Tivo. Your Tivo only supports SDTV because it doesn’t have an HD tuner, plus can only output s-video. You need HDMI or component to output HD.
If you want to record HD, you have two options:
1) Buy a Tivo Series3 HD.
2) Rent Comcast HD DVR. Only $5 extra a month.
With your Tivo, you are stuck being able to record only SD stations. Connect your Tivo to your cable box via s-video. Connect the Coax to your cable box. That should allow you to record shows and watch HD on your Tv.
I don’t know what you mean by HD cable, but I’m sure your Tivo doesn’t have HDMI outputs. Just use the best cables it has, component, s-video, whatever, that’s all you can do.
I know you said not too, but if you spent the money on a 50″ 1080p tv, you wasted your money if you don’t get the HD version. Can you even pick up HD with that box??? If you’re gonna do it, don’t go half way. Trust me it makes all the difference in the world
