ZikZak- Thanks again for your response. After pondering what you wrote, I think I'm going to:
1) split the cable for two feeds
2) one feed to the 6412 for pure digital and HD - using hdmi to the tv
3) the second feed to the TiVo for SD on whatever channels the TiVo will recognize without a cablebox (2 to 80-something, I think) - using s-video to the tv

That's my setup....except I've got the 3412 from Comcast. The TiVo doesn't look great on my 42" Sony, but it's watchable.

Tivo needs to either come out with their own HD box, or get their software on the Comcast box ASAP! I need my HD!
