I believe that the HD search parameter that was added to the Category Only WishList selection in version 8.3 of the software for the S3 was a huge improvement. Alas, it does nothing for those of us who want to find programs, which, although not in HD, are presented in letterbox. Although 16:9 SD isnt in a class with HD, its a whole lot better than 4:3 SD, it seems to me, especially for movies. I did a little research before I posted and learned that the old DirecTiVo apparently had a search parameter for Audio & Video and a subcategory for Letterbox. Here is a link to that thread: http://www.tivocommunity.com/tivo-vb/showthread.php?t=308082 Thus, it appears that such a "Letterbox" parameter could easily be added for those of us who use S3s. I hope that TiVo is listening and gets it done.
