Just back to TiVo after three years in Scientific Atlanta purgatory. Love the Roamio plus so far (even though I've had to drop back to 5 tuners). Something I noticed straight away...TiVo doesn't seem to know that when I select channel 2, it should (behind the scenes) auto tune the HD version which is channel 702 here (Cablevision in Westchester county, NY). As bad as the SA DVR was, as least it knew to do this. I deselected all the non HD channels in the guide, which helps with clutter. But...still a tad frustrating since everyone in the family is used to certain channel slots and some don't match so neatly (eg YES is 70 in SD but 715 in HD). Anyway to use the lower number channels and have the TiVo auto tune the HD versions? TIA.
