Advertisements On my series 3, I have to manually go through 800 channels and write down which channels I don't receive, go into the TiVo settings and uncheck the channels, which takes forever. Does anyone know if the TiVo Premiere supports cable card channel scanning? If not, does it at least support channel previews from the channel list screen so you can see if you can tune the channel or not? The current implementation is really poor. This may sound silly, but I'm using this as my litmus test for buying a TiVo Premiere. If they cared enough about improving basic user experience to fix this issue, I'll buy one. Edit - This is also annoying since Comcast keeps on adding random channels that I don't receive, so every few months I have to flip through all my channels and write down all the ones I don't get and go through the settings menu. This is a constant issue, not a one time setup thing.
