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