Advertisements Configuration: TW cable w/basic service (22 channels) + TiVoHD + broadband connection via RR. Here's the issue: With basic cable, we also get "free" HD channels like 1813 for NBC-HD. For some reason, TiVo sees these HD's as decimal channels, like 18.13 (or 18-13). The channels are in the channel list after you allow TiVo to scan its coaxial connection, but only as decimal. The guide does not recognize these decimal channels. I have read some conflicting posts on the use of CableCARDs enabling TiVo to see these HD decimal channels in their native non-decimal form, and thus improving the possibility that the guide will see 1813 as NBC-HD. Please comment, thanks!
